Harmless Obsession for the Captivating Male Lead

A three year old.

Too young to make sense of reality.

Nonetheless, a three year old suddenly became aware of herself. Without any forewarning. Rosenia was just shaking her toy…

‘No way…!’

Memories began to become entangled in her head.

It was none other than the memories from her previous life. The memories made her see reality differently.

For example, the world Rosenia was reincarnated in is actually a novel, and she’s the younger sister of the villain who will one day die by the male lead’s hands!

‘This can’t be…’

Thud. The snake-shaped toy Rosenia had been holding in her hand fell to the floor.

At the noise, her wicked older brother, who was sitting next to her and reading a book, looked at her. His crimson eyes glowed unnaturally as he glanced over at her apathetically.

“What’s wrong?”

“…”

‘How can someone ask a three year old in that manner? I tried to hide my chills while putting on a smile.’

Then, her wicked older brother, Adrian, snorted as if dumbfounded and magically lifted the toy snake.

A normal three year old would have gasped. And Rosenia would have been surprised too, if not for the memories from her previous life making her feel uneasy at such a sight.

‘I can’t believe you’re using gravity distorting magic so easily…You’re only seven years old.’

As Rosenia had expected, the talent of the villain in the original novel is terrifying.

With trembling hands, Rosenia grabbed the toy snake floating in the air. Her wicked old brother, who is four years older, will one day succeed their father and become the youngest member in the Mage Tower.

But perhaps because of his evil nature…he will be killed by the male lead for causing all kinds of harm to the world!

‘As for me, I’ll die along with him.’

At a loss for words, Rosenia listlessly shook the toy snake and let out a deep sigh. She thought she’d be reincarnated with a golden spoon, but it turns out to be a plastic spoon.

If the plot follows the original story, her death is as good as certain. Rosenia will pitifully die by association because of her wicked older brother.

Suddenly, Rosenia thought of how she could survive.

Like the heroine in many of the romance novels Rosenia had read in her previous life, she thought she could tame the villain.

Her evil brother, the crazy person over there, who was reading magic books even old scholars would find difficult.

‘Kill…this damn guy…?’

‘The three year old me…?’

“…”

“Why are you staring at me like that? Are you hungry?”

There was no fluctuation in his tone. His face was expressionless, and his crimson eyes were cold. Rosenia didn’t doubt that he is the same as in the original novel, a cold-blooded psychopathic villain.

‘How am I supposed to tame him?’

‘Damn it, I quit. Let’s just quickly die.’

Rosenia threw the toy at his face, hoping that her wicked older brother will soon kill her.

The long toy snake accurately hit her wicked older brother’s face. Rosenia was certain he would kill her after that humiliation.

‘Alright, go ahead and kill me.’

Having resigned herself, Rosenia waited for his magic attack to come. Her only wish was for him to kill her quickly and painlessly.

‘I’m sure you’ll show at least that much mercy to your own little sister, right?’

“…”

However, no matter how long Rosenia waited, the attack didn’t come.

‘What…?’

Rosenia crept up and timidly looked at her wicked older brother. He was deep in thought as he stared at her, then he said something out of her expectation.

“You wanted to learn gravitational distortion magic?”

‘Huh?’

‘No, I just threw a toy in your face with all my might.’

“As expected of my little sister…You’re also a genius.”

“…”

‘This damn guy, what are you saying…’

Her wicked older brother sat her on his lap, then he opened up an easier gravity magic book than the one he had been reading.

‘Are you going to ask me to read these tiny letters?’

“If you’re a genius, you won’t find this difficult, right?”

‘You crazy bastard…How old do you think I am?’

It was clear that the fact Rosenia is a three year old has never crossed his mind. Inwardly cursing her ancestors, she looked down at the book.

Although Rosenia didn’t know if she could read this difficult magic book, she knew she had to pass this test if she is to have any hope of getting close to her wicked old brother.

Rosenia touched the first page with her tiny hands and began to read slowly with her poor pronunciation.

“Fishy, to cat gavty dishortion mashic, the mana paf…”

‘Firstly, to cast gravity distortion magic, the mana path…’

Surprisingly, Rosenia found that she didn’t have any trouble reading the letters.

‘O-oh my god, am I a genius? Or is this my golden spoon? If not, perhaps it’s thanks to my memories from my previous life.’

The problem now was whether her wicked older brother understood what Rosenia had recited or not.

For a three year old to read this much was simply incredible, but it was inevitable that her pronunciation would be poor.

And sadly, her wicked older brother, who has a screw loose, seems to not have much common sense.

‘My pronunciation as a three year old, I wonder if this damn guy understood…’

“You…”

Her wicked older brother, Adrian, stared at her profoundly, then he spoke in a slightly stunned voice.

“You’re a genius.”

“…”

As a three year old, Rosenia knew her pronunciation would be poor, but unexpectedly her older brother was able to understand everything she had said.

So just like that, Rosenia was able to pass Adrian’s first test. A stroke of luck in the midst of misfortune. Adrian seemed quite pleased with the fact that she is a genius just like him.

Ever since that incident, Adrian’s actions changed and he would take her with him wherever he went to show her the world.

Not only that, Adrian even told their father that he would oversee her magic education himself. Rosenia gave her father a frantic look right then and there.

‘Father, don’t allow this! Don’t leave me to this lunatic!’

“Rosenia seems eager to learn from you.”

‘What? No!’

‘Idiot father! Did you not see your daughter’s eyes?!’

“I guess it’s because Rose loves me.”

‘No, when did I…?! You’ve got it wrong!’

“I’m glad that you two are getting along. Then please look after Rose’s education. Adrian.”

‘Oh, no way…! No, I don’t want to learn from my older brother who is a villain!’

Rosenia quickly ran to her father’s side to grab the hem of his pants and begged.

“Aye!”

“Huh? You can’t wait to learn?”

‘No, I don’t want to! Did he not hear me say no?’

“Rosenia’s enthusiasm for learning is great. Go ahead and teach her, Adrian.”

“Okay.”

‘Oh my god!’

Adrian came and lifted her up. Rosenia had no choice but to grab him by the collar and curse him inwardly.

“You damn villain… How much are you going to ignore me?’

‘Just wait. Now that it has come to this, I’ll tame you and make you wipe my foot!’

With a firm determination, Rosenia had been doing her best to tame Adrian ever since.

Thanks to her hard work, he grew up with a relatively mild temperament. That is, when compared to the original plot.

In other words, it is relative. Adrian’s nature didn’t change much from when he was 7 to now when he is 24 years old.

He is still cold-blooded, but now has become the youngest sorcerer elected to the Mage Tower and has made a name for himself.

And Rosenia was now known as Adrian’s precious younger sister hidden in the mage tower.

‘It’s like I’m Rapunzel…’

His overprotectiveness is so intense that even though Rosenia is almost 20 years old now, she hasn’t even properly set foot out into the real world.

Adrian would accompany Rosenia everywhere she went.

‘I only wanted to tame him a little bit, but…did I overdo it?’

Adrian had a very serious sister complex.

‘I need some fresh air!’

It was almost summer and Rosenia wanted to visit the villa by the seaside.

However, Adrian was too busy to go. That was precisely the problem.

Adrian, who always tries to accompany Rosenia wherever she went, did not allow her to go down to the villa by herself.

This time too, Rosenia begged him, but he just calmly smiled and dismissed it, saying ‘No way.’ She was outright denied.

‘Damn it, you crazy bastard with a sister complex!’

Rosenia tore a paper into pieces while imaging Adrian’s jet black hair. Living with a person who has a sister complex was so stressful that tearing up papers like this from time to time became her hobby.

‘It’s so stuffy staying in the tower during summer! Is there any way?’

Feeling dizzy, Rosenia laid down in the middle of the room with a deep sigh. The pieces of paper were scattered like feathers.

‘Is there really no way…?’

Out of nowhere, an unthinkable opportunity appeared. At the Emperor’s request, Adrian had to go investigate the beast outbreak in the Southern Coast.

‘Suffering at the hands of my older brother who has a sister complex, did God find pity on me?’

“Brother! Let me come with you!”

Boom!

Rosenia shouted loudly as she broke through Adrian’s office door.

Having mastered gravitational distortion and strength magic since she was three years old, she has become so powerful that her breaking the door whenever she was excited is a common occurrence.

Rosenia gave an embarrassed smile as she placed the broken door upright against the wall. Adrian looked at her dumbfoundedly.

“Haha, isn’t the door a little weak? You should have something stronger, brother.”

“…”

Looking at her with his crimson eyes, he scoffed.

‘It’s unfortunate that this human in demon skin is very handsome.’

Jet black hair, red pupils, and snowy white skin created a mysterious atmosphere as if he was not from this world.

“You also want to investigate the beasts?”

“Uh…do I have to? I just want to go to the villa and play! I couldn’t go last summer. I don’t want to be stuck in the tower again this year.”

At her words, Adrian gave her a deep look as if he were briefly thinking of something. Then, after some time, he spoke.

“Okay, I’ll take you along.”

“Wow! Thank you, brother! I love you!”

“…!”

‘I love you.’

Adrian was weak to such words. To be exact, he was weak to her saying it. It was when Rosenia was around three years old that she discovered this magic spell.

It was when she said ‘I love you’ to Adrian for the first time. It gave her goosebumps when the words left her mouth and she thought she was going to die for saying it. However, it was Adrian’s birthday that day and she thought she should give him something special other than presents.

‘That’s how I’ll be able to change this wicked older brother into a human being!’

‘The first time he heard ‘I love you’ from his younger sister, his reaction…It’s so funny thinking about it again. His face was as red as an apple. This very same Adrian.’

‘Huhu, even now…’

Rosenia has used the words ‘I love you’ for over a decade. Perhaps that’s why Adrian has gotten used to it, but his ears still turned red.

This time as well Rosenia checked the tips of Adrian’s fluffy ears and laughed wickedly to herself.

‘This damn guy will never know. The fact that his lovely, cute, and beloved sister is actually the reincarnation of a black-hearted person. ’

‘Huhuhu…’

While inwardly laughing, Adrian gave a short cough, then returned to his calm expression and spoke.

“So you will just stay at the villa. Absolutely don’t go anywhere else.”

“Yes, got it!”

Rosenia had already decided to sneak out and look around the market.

“I’m going to give you a familiar for protection, so take it with you everywhere. When you go to the bathroom, when you go shower, and even when you sleep.”

‘You crazy bastard…’

Rosenia smiled lovingly and nodded like a good little sister.

“…Then go pack your bags. We leave tomorrow.”

“Yay! Thank you so much, brother!”

Excited to travel to the Southern Coast, Rosenia shot back to her room like an arrow and started packing.

White sandy beach, open sea, and a beautiful seaside villa along the coast.

Not even in her wildest dream could Rosenia have imagined who she would meet there.
