It was a time when Olivia was 10 years old.

"Damn it."

Olivia, with her chubby cheeks, was frowning at the mirror.

"Daaaamn it..."

With a great deal of anger.

10-year-old Olivia hated the world.

"Heehee... heeheeheeek!!!"

Because she thought the world was unfair.

"Damn..."

Why does the body gain weight?

Sweet things make you gain weight quickly.

Why don't tasteless things make you gain weight?

Salads.

Greens.

Bell peppers.

They're all tasteless, but why do they make you healthy when you eat them? 10-year-old Olivia, biting her lip at the damn order of the world, was looking at the mirror and spewing curses.

Someone had asked Olivia.

-Young lady, why is your mouth so foul?

Why was her mouth so dirty, unlike a 10-year-old child?

-No one even taught you, but you're saying 'damn, damn...'.

-Eek?

-Neither the family head nor Rosanna-nim... not even Kyle-nim curses, but it's ironic that only the young lady curses.

She wanted to say a word to the commoner who was questioning the speech of a noble, but in those days, young Olivia, in order to maintain the dignity of a noble, had answered like this.

-Because I'm pretty.

-I don't think so.

-It's okay for pretty people to curse.

-You've decided to just ignore me now, haven't you?

Because she's pretty, she can curse.

In fact, Olivia, who could curse at an earlier age than anyone else thanks to the 'villainess' gene passed down through the Desmunt family, was Olivia of that time who didn't know the reason even after becoming an adult because it was a secret she would realize someday after having her own child.

Anyway.

"Daaaaaaamn it!!!"

Young Olivia was looking at the mirror full of her chubby cheeks and admiring her venomous face.

"Oh..."

Her chubby cheeks could be called a thorn in her side, but.

"Oooooo!!!"

She could say one thing for sure.

"I'm pretty."

The fact that she was the cutest creature in this world.

Chubby cheeks.

Venomous eyes.

A light blush and flaring nostrils.

"I'm really pretty..."

Olivia, who had judged that no one in this world could beat her cuteness, was wearing a pleased expression with a smile rising from the corners of her mouth.

What person in this world could have a complaint after seeing her face?

"Uheehee..."

The cutest person in the world was standing right in front of the mirror.

"Mirror, mirror, am I pretty?"

In those days, Olivia was in the final stages of princess syndrome.

Olivia, who was at the age of talking to the mirror, was making a seductive expression with her dolls as the audience.

"Uuuuuuu..."

She would try to wink.

-Wiggle wiggle.

She would flare her nostrils and show off her healthy beauty.

Olivia, who was imitating adults in front of the mirror for a long time, was making a serious expression, but.

"You look like a pink pig."

At the boy's words, who was watching everything, Olivia, whose mood had been dampened, frowned and clenched her fists.

How dare a commoner call a noble, who was standing so seductively, a pig? She wanted to poke the impertinent commoner's eyes with her finger.

"Eeeeeek!!!"

Olivia, who had clenched both her fists, got angry at the commoner who had insulted a noble and began to run.

-Dododododo!!!

The target was the kid who had called her a pig.

"I'll kill you!!!"

The probability of winning was 100%.

When she had picked him up, their strength was about the same, so she thought she would naturally win, as she ate only good things and slept 12 hours a day.

But.

"What are you doing?"

Olivia was waving her hands in the air, with her forehead pressed against the kid's hand.

This was the difference in growth.

10-year-old Olivia hated the world.

"Pooooooo...."

"Oh my."

"Pooooooooooooo!!!!"

"To puff out your cheeks, you're shockingly cute, but that kind of aegyo doesn't work on me."

"Don't call me a pig!!"

"Then I'll call you a guinea pig."

"Guinea pig?"

"A small pig."

"...Damn!"

Young Olivia sincerely disliked the kid.

"Die!"

"Oh my... I was about to die, but I'm alive because the young lady picked me up."

"Then.. then...!"

Olivia, who was trembling her eyes as if she was in trouble, just clenched her fists and hit Ricardo's chest.

It didn't seem like she could win against him with words.

"Eeeeeeeek...!"

She had definitely learned more and studied more, but for some reason, he was using sophisticated vocabulary that couldn't come out of a beggar's head.

"You poop head!"

"Calling someone a 'head' is not a correct expression. As if I'm a fish, you call me a 'head'? I'm a Desmunt servant, after all."

"...Eeeeeek!"

Olivia was getting annoyed to the point of her head exploding at the inconsiderate kid's behavior, who didn't lose a single word.

After hanging onto Ricardo and throwing a tantrum for about 30 minutes.

"Here."

"...Uing?"

Olivia's eyes widened at the small piece of chocolate Ricardo was offering, and she began to flare her nostrils.

"It's a snack."

"Heek?!"

"You don't want it?"

"No..!"

Olivia, who quickly snatched the chocolate from Ricardo's hand, opened her eyes wide and began to smile. She thought that if there was anything in the world that was not wrong, it was her own stubbornness and the perfect food called chocolate.

"Heehee..."

Ricardo, who was sitting next to her, took out another piece of chocolate from his inner pocket and began to put it in his mouth.

-Crunch.

"It's too sweet."

"..."

"It's so sweet that my teeth will rot, so I don't understand why you like chocolate so much."

Such an unreasonable person.

"That's why you're no good, Ricardo."

"I don't think I'm as bad as a guinea pig."

"...Don't call me a pig!"

"Isn't it harsh to not treat me like a person just because I don't know the taste of chocolate? I've never even eaten chocolate before, since I'm from a poor background."

"Eeeeeek...."

Olivia, who had glared at Ricardo once, squeezed her eyes shut, broke the chocolate into pieces, and offered it to him with a trembling hand. Since he said he hadn't eaten much, she wanted to feed him a little more and let him know the taste of chocolate.

"Hmm?"

"Eat it."

"Are you giving it to me?"

"Ung."

"Pfft..."

"What...?! Don't laugh!"

"Isn't that a little too little?"

Ricardo let out a laugh as he looked at the small piece of chocolate on the tip of Olivia's finger, saying that even an ant wouldn't be able to taste this much.

"Why are you complaining even when I'm giving it to you!"

"No, no."

Ricardo gave a faint smile, put the chocolate Olivia had given him in his mouth, and nodded.

"This is more delicious."

"Right?"

"Exactly."

Giggle. Olivia, who had smiled, looked out the window and gave a faint smile.

"See. I told you chocolate is delicious."

"You're right."

"From now on, be nice to me. Got it?"

"Yes."

Ricardo opened his mouth.

With a soft voice, telling a story that would ruin the taste of chocolate.

"So, young lady."

"Ung."

"How long do you have to be locked up here?"

"..."

That's right.

"You slapped the crown prince's cheek."

"...Eek."

"I told you not to fight like that."

"No."

In fact, Olivia was being scolded.

Olivia spoke to Ricardo, who was scolding her, with a pout.

"He said something about what I was eating."

"What did he say?"

"He said to stop eating... that the empire was facing a famine because I was being so extravagant, so how could I endure it?"

"He deserved to be hit."

Olivia, who had flared her nostrils, nodded at Ricardo's affirmation and clenched her fists, thinking that only her family and Ricardo understood her.

"Then you ate a lot today."

"Yeah."

"I thought you hadn't eaten anything, so I brought you chocolate."

"...Ung?"

"Hmmmmm?"

The moment an ominous premonition rose from the tips of her toes, Olivia shoved all the chocolate left in her hand into her mouth and kept her lips sealed.

"Ubu,,,"

"...I'm not taking it."

"Ubuubu."

Ricardo, who smiled at Olivia's square, ruined cheeks, knelt down and said.

"Just stay healthy."

"U bubububu (I'm healthy.)"

"Just like now."

"Ubuubu. (Ricardo.)"

Olivia pulled on Ricardo's clothes and said.

"Ubuububububu!!! (The chocolate is stuck in my throat.)"

"...Haa."

"Ekegekegekegeke!!!!!"

It was an eventful day at Desmunt.

*

And so, now.

"Haaaam."

Darbab was looking at Olivia with a lazy smile.

"Are you tired?"

At Darbab's question, Olivia shook her head and smiled.

"No."

In front of her was the burning sanctuary of the heretics.

Numerous heretic priests were trembling in fear as they looked at her, and she just looked at them with cold eyes.

Olivia, with a lazy expression, looked at Darbab, who was subjugating the heretics of the east, and opened her lips, with the worry that her father would be more tired.

"You're more tired, father."

Darbab gave a small smile and waved his hand.

"A father is not tired. I don't know how I can think that I'm tired when I'm with my daughter."

"..."

"I'm just sorry for showing you such a bad side of me."

"I asked for it, so why are you sorry, father?"

"Still."

Olivia shook her head at Darbab's dark expression and opened her lips once more.

"Father."

"Why do you call me?"

"You can't tell Ricardo."

Darbab nodded and answered.

"I won't tell."

"..."

"It will be tiring if that guy finds out."

Olivia had asked Darbab for a favor.

-Father, I want to become stronger.

To arrange an opportunity for her to practice black magic without Ricardo knowing.

Darbab had refused Olivia's request to use the profane power, but he was no match for Olivia's stubbornness.

-I don't want to be a burden.

-Still, you can't.

-I have a disability.

-...

-I'm already sorry for being a burden, but becoming a piece of shit is not what Desmunt is about.

Because the only person who could break Olivia's stubbornness was him.

-You can't overdo it.

Darbab had no choice but to give in to Olivia's stubbornness.

Olivia needed the strength to protect Ricardo, who was always getting into trouble. At the very least, she didn't want to be a burden to him. In the first place, she was a burden because she had too many enemies.

"Olivia."

Darbab gave Olivia a faint smile and held out a square box.

"Oh..."

Chocolate.

-Crunch.

Olivia, who had bitten into the chocolate, nodded and smiled.

"It's not as good as the one I ate back then."

"Hmm...? I bought the shop and made the chocolate with the old recipe, so is it strange?"

At Darbab's words, Olivia shook her head.

"No. I'm just saying."

The memories were sweet.

-Crunch.

Sweeter than any other chocolate.

-Shoaaaaaaaa.

"Haa... Haa..."

The academy's bathroom.

Yuria, looking at the mirror in front of her with trembling eyes, frowned as she felt her heart pounding.

"Why is my chest... like this?"

The pounding of her heart, which couldn't be masked even by the sound of the rushing water, was weighing heavily on Yuria's mind.

In Yuria's ears.

-Kill...

She was hearing strange voices.

-Kill them all.

Before meeting Ricardo.

Yuria had started her morning with a nightmare.

Of herself standing alone in a desolate place.

-Help me.

And a nightmare of herself standing on a mountain of corpses.

In the nightmare, she was smiling.

And the corpses were all familiar people.

Shartia.

Schuen.

Mikhail.

And.

-Let's stop this now.

Ricardo.

In the nightmare, she was smiling.

As if their deaths were her happiness, she was enjoying their screams.

It was such a vivid dream that her whole body was soaked in sweat, and it was such a terrible nightmare that she never wanted to have it again.

It would have been better if it had just been a nightmare, but.

-Kill.

After waking up from the dream, Yuria began to hear strange voices in her ears.

The voices she heard in her ears tormented her emotions.

Because the voice that urged her to 'kill' was so sweet that it felt blissful, going beyond an unpleasant feeling.

If I kill people with these hands.

If I kill Shartia with these hands.

It's natural for the countless movements of killing intent and impulse to be unpleasant, but.

"Hoo..."

Strangely, that voice sounded sweet.

The scariest thing was...

-Yuria-ssi?

Meeting Ricardo.

When she met Ricardo in the hallway, Yuria felt an indescribable nausea.

She had been barely holding it in, but the moment she saw his face, a mad emotion began to well up.

-Kill.

The voice that echoed in her ears grew stronger.

-I said kill.

Every time she heard his voice, the overlapping whispers began to sound sweeter.

It was unpleasant.

Me, who harbored such emotions.

And at the same time, Ricardo's voice too.

'I feel like throwing up.'

It felt so unpleasant that she wanted to cover her ears.

-Is something wrong?

Normally, I, who would have struck up a conversation with him because I wanted to talk to him, felt a sense of fear at how uncomfortable his concern, which he uttered, felt, to the point of making me angry.

This is different from the usual me.

This is not what I think.

-Kill.

Along with the chilling voice in her ears, it felt like a mad hostility towards Ricardo was welling up.

Yuria raised her trembling eyes and looked at herself in the mirror. Because with her own eyes, she should be able to detect the abnormality in her body.

With the divine eyes that see the abnormalities of health.

"It's probably nothing...."

Because she should be able to find where it hurts.

Contrary to Yuria's trembling eyes' wish, her reflection in the mirror showed nothing.

"...Ah."

Despairingly.

"Ugh..."

Yuria, who was looking at the bathroom mirror with a feeling of her stomach turning, went into an empty stall to throw up.

-Creak.

After she went in, Kaila, who came out of another stall with a small smile, felt a thrill and muttered under her breath.

"It's done."

A smile was on Kaila's lips.

*

'The black magic seems to have succeeded....'

-Step.

'The book said the effect would appear slowly, so if I just wait about a week....'

-Step.

'I can get my place back...!'

A price placed on the scales is not lost at once.

Lifespan.

Mana.

Money.

The book stated that the 'price' placed on the scales was taken according to the speed of its manifestation.

A minimum of one month.

A maximum of three months.

If she waits this long, Yuria will be broken along with the price she offered.

The idea of seeing both of them break at the same time wasn't very appealing, but Kaila, whose lips were smiling at the thought of seeing the fallen Yuria, began to walk towards the dormitory with high expectations.

'That place was supposed to be mine.'

With a smile of being able to regain what she had lost.

There were four prices placed on the scales.

10 years of lifespan.

The 'mana' to use magic, and the emotion of 'love'. And one of her body parts.

It was fine even if it disappeared.

Mana could be obtained by hiring people with money, and her looks were like magic anyway, so she didn't want to live a brutish life using magic.

As for lifespan, it was fine to die in her most beautiful years.

A life where she had everything would be much more valuable than a mere 10 years, so Kaila, who had invested a mere 10 years in the future, had no regrets.

In the first place, the emotion of 'love' was a luxury for nobles.

'This is a cheap price to pay... It's better than getting caught and going to prison.'

She didn't love Tae-oh.

All this jealousy stemmed from the desire to conquer him, who had the looks, the backing, and who rejected her.

To be precise, it was possessiveness.

The desire to have what you can't have.

What tilted the scales the most was offering one of her body parts, but since she hadn't put anything on the scales that would interfere with her beauty, she didn't have to worry about it much.

Life might be inconvenient, but it wasn't a waste if she could see that bitch's downfall.

"It's all mine."

Kaila, whose pride was hurt that she had to make all these sacrifices for a mere commoner bitch, bit her lip and walked forward with the thought of seeing her downfall with her own two eyes.

-Step.

Just as she was about to reach the park leading to the dormitory.

"..."

Kaila saw a woman sitting on a bench.

'...Who is that?'

The woman sitting on the bench looked at Kaila, then slowly got up from the bench and began to approach.

"It's been a while, Kaila."

A young woman, not wearing a uniform at the academy, was speaking to Kaila with a chilling expression.

-Step. Step.

Kaila's pace quickens.

"Where are you going?"

Without answering the question that stopped her.

-Step. Step. Step. Step.

Kaila began to walk quickly back the way she came.

"Kaila..!!"

The woman in front of her knew Kaila. Likewise, Kaila also knew the woman who was following her.

-If I just do that, I can be with Mikhail, right?

-Right, if only Yuria wasn't here, you and Mikhail could be together.

-Really?

-Right, there's no one at the academy who's as good to Mikhail as you are. Mikhail definitely likes you too, but he can't approach you because of Yuria.

-If only Yuria...

Because that woman was a pawn to abandon Yuria in the dungeon.

"Kaila!!!"

As the sound of the woman's footsteps, approaching with a chilling shout, grew closer, Kaila began to walk urgently towards the academy building.

'That moron...'

How did she get in here? Kaila couldn't help but think that the damned academy security was so lax. To the point where she thought she should tell her father to overturn it soon.

'Go away...'

She thought she was in danger.

Kaila at that time.

-Kaila!!! You're the one who ordered all of this!!

-What are you talking about? Yuria, are you okay...?

-You... you... I won't let you get away with this.

Because she had just used her as a pawn.

She thought she had given her enough money.

-This is enough for you to have made a living, considering you were expelled from the academy.

-...

-Don't want to take it?

-...

-You commoner.

-I'll get my revenge.

-Try me. Then I'll make your family disappear from the empire without a trace.

Kaila, who saw the approaching figure with a pale face, as if she had run out of money, bit her lip and started to run. She began to let out a ragged breath, feeling impatient at the mana that wasn't gathering at her fingertips.

'M-my mana...'

She thought it was dangerous.

Kaila thought she might die if she was caught by that woman.

"Stop...!"

Just as the footsteps of the woman following her were about to catch up to her own.

"What are you doing?"

A familiar voice began to be heard in her ears like a salvation.

-Clang.

A strange sound is heard.

The clear sound of a blade falling to the ground.

"...!!"

Kaila's eyes trembled as she looked at the blade that had fallen to the ground.

And.

"...Let go!!!"

The voice of the female student who had been following her began to be heard loudly in her ears.

The shadow of a hand waving, along with a flailing gesture, was clearly visible in Kaila's eyes, who was looking at the ground.

"I'll kill you!!!"

"..."

"I'll kill that bitch!! If it wasn't for that bitch, Mikhail and I could have been together...!"

The moment Kaila was frozen in place, unable to say a word, drenched in fear, the man who had saved her ended the situation with a chilling voice directed at the woman.

"Do you want to die?"

"..."

"I really do kill people."

"..."

Adding a greater killing intent to the killing intent.

-Tap tap tap.

Kaila, who let out a sigh of relief along with the sound of running footsteps, was about to offer her thanks as she watched the woman's departing back.

If it weren't for you, I might have died...

But.

"Student Kaila."

The damn coincidence had her facing the man she hated the most.

"Are you alright?"

"...Professor Ricardo."

"That was a close call."

A short silence ensues.

"Thank you. Then..."

Just as Kaila was about to leave with a quick thank you, the man's chilling voice was heard from behind her.

"Magic."

"..."

"Can't you use it?"

"!!!"

The man said to her.

"Haa..."

He let out a deep sigh.

"What have you done?"

He began to recite her misfortune.

"You'll die."

"..."

"For real."
