It was too bright.

Rin cringed as the sunlight was peeking through the gap of her curtains and shone on her face. She tried opening her eyes, only to close them again due to the sun's glare.

Rin groaned and turned to her side, away from the light. Just as she about to fall back to sleep, she suddenly felt a gentle blowing on her face. She noticed there was another presence in her bed, making her freeze.

Since her eyes were closed, she didn't know what -or who- was beside her.

Rin slowly opened her eyes which then widened and she screamed when she found a familiar face sleeping right beside her. His face incredibly close to hers that the tips of their noses almost touched.

Rin jumped off the bed and stumbled backwards until her back hit the wall. Her mind was still blurry from sleep so it took her a few minutes to recognize who the intruder was before she exploded. "What the heck are you doing in my room Len!" She yelled at the blond haired male who sat up and yawned.

He tiredly looked up at the brown haired female and said. "Oh...You're awake." Len yawned as he rubbed his eyes. Rin glared "Yes I'm awake and before I kick you out of my room, let me ask again." She threatened.

"Why. Are. You. In. My. Room?" Rin demanded, stomping forward in every word. Len yawned again before smiling lazily. "To wake you up for school of course." He said simply.

"Then why were you sleeping on my bed?" Rin asked but a more important question popped into her head. "And how did you even get into my room in the first place?" She was sure she locked the door...

"Spare key." Len said as if it was the most simplest thing as he pulled out a shining silver key.

Rin frowned and snatched the key from his hand. "And to answer your other question.." He continued. "You just looked very peaceful sleeping there that I didn't have the heart to wake you, plus you were very cute in you're a sleep" Len grinned flirtatiously causing Rin's eye to twitch in annoyance.

"That still doesn't explain why you were asleep right next to me." She grumbled, crossing her arms. "Oh." Len uttered. "Well, I must have fell asleep while watching you" He said sheepishly as he scratched the back of his head then he looked straight at her, a strange glint flash in his eyes that told Rin that she won't like what comes next. "By the way I never thought you had sleepwear like that."

She looked down at her short white nightdress. It didn't cover much of her legs and arms, and merely stopped to her mid-thighs. Rin blushed deep red and threw a pillow at him. "Get out!" She shouted, pushing Len out the door and slamming it shut.

Rin grunted and leaned her back against her door. Sighing she slides down it. Really how did she ended up dealing with him like this anyway?

It started a week ago...

"No! You can't do this to me!" Rin yelled desperately as she watched her parents pull out her things and suitcases from their car. "Honey, relax..." Mrs. Kagami said, placing a comforting hand on her daughter's shoulder. "It's only for a year and a half."

"But you can't leave me alone with a boy with no adult supervision!" Rin exclaimed then grimace. "Especially with him!" The two glanced at Len who was helping Rin's father with the cases, noticing them looking at his direction.

Len grinned and waved. Mrs. Kagami smiled and waved back except for Rin who glared before turning back to her mother. "It's not going to work out well Mom..."

"Why not?" Mrs. Kagami frowned. "Len's a sweet boy! I'm sure he won't hurt you"

Rin scoffed. "Mom you don't know him like I do, he's-"

"I think your mother's right Rin." Mr. Kagami cut in as he approached the pair. He smiled, giving an apologetic smile to her daughter when she turned to him with a look of shock and betrayal.

Rin knew her father was over protective when it comes to her (though its a pain sometimes) so she thought he would be with her on this matter, not against her.

"Though I don't approve leaving you at the hands of a boy." He muttered before quickly adding when he saw the look his wife gave him. "I think you'll be perfectly fine with him, besides you've known him for years! He's a true gentleman"

In what universe? She thought.

Yes, it true she's known Len since they were kids but she still couldn't trust him for different reasons. "But why do you have to leave me with him?" Rin questioned. "I can take care of myself at home so why make me move in with him?" Her parents glanced at each other before turning back to Rin.

"Well." Her mother started. "You see Len's father...don't actually trust him with the house" Rin tilted her head in confusion, her mother sighed.

"I'm not sure about the details but apparently, Len had caused a huge mess when his father wasn't around. It seems like he had hosted a large party at their house." Rin blinked and look of recognition appeared on her face.

"Oh." She muttered. She remember that. Len was telling the whole school that he was having a party at his house- or mansion- it was a very wild party from what she heard and from really good detail at that.

Some of the windows were shattered, food, drinks, and junk were scattered everywhere, and several people were asleep in peculiar places like the floor or front yard. It was probably the biggest party Len has ever hosted. Rin, on the other hand, didn't really attend and stayed at home, studying.

"Still you can't go away and leave me here to babysit the guy" Rin reasoned.

"Rin, enough" Her father said sternly. "You are going to stay with him until me and your mother comes back from our business trip. The only people we could rely on right now to look after you is Len and no one else."

Rin frowned. She understood that both her parents were working hard as a pair of business workers but still, she could manage well on her own in their house since she was already a responsible 16 year old and she just didn't understand why she had to be left alone with Len, of all people.

"But-!" Rin started but stopped when she saw the look her father had. Rin pouted then huffed and mumbled some things before she opened her mouth again to protest some more when an arm wrapped around her shoulder making her to stop.

"Don't worry Mr. and Mrs. Kagami!" Len exclaimed cheerfully. "Your daughter's in safe hands I promise you that" Rin's parents smiled at that while Rin stood there like a statue. They were really going to leave her with this...this...person! Rin paled at the thought.

Mrs. Kagami then checked her watch. "Oh! Darling, we have to go before we miss our flight." She said to her husband and turned to them. "We don't want to miss our flight so we'll leave her to you, alright?" Len nodded happily at that.

"Rin, we'll call and text you as much as we can okay?" Mrs. Kagami said comfortingly though was unsure whether or not she was listening from how quiet her daughter was, but nevertheless kissed both her cheeks while Mr. Kagami patted Len's shoulder before retreating back to their car.

By the time they drove off. Rin snapped out of her daze, pushing Len away from her before running after her parents. "Don't leave me!" She yelled after them but it was too late as they disappeared into the distance...

'And here I am babysitting the most obnoxious guy in the planet! Ugh, God kill me now!' She thought as she straightened up her blouse. She looked over her large wall mirror to see if she looked proper enough. When she thought it was fine, she walked over her desk to get her hairbrush from the drawer.

Rin paused in front of it when she saw the key shining from the light, she frowned deeply as she stared at it.

Yes, she knew this was his house but he still had no right to barge into a girl's room and watch her sleep!

That is really creepy. If he had a spare key to her room in the first place then that means he could have easily enter and leave her room without her knowing. Rin shuddered at idea. What else has he been doing that she doesn't know of?

She shook her head to dismiss the thought and opened up her drawer for her brush.

"Took you a while sweetheart." Len remarked as he waited at the bottom of the stairs while Rin walked down towards him. "Shut up playboy." Rin growled as she walked passed him and to the kitchen.

Len simply smiled and followed after her, where Rin grabbed an apple. Len leaned against the island counter in the middle of the kitchen and watched as Rin bit into it. He looked at her from head to toe. Her lovely face to her slim figure to her long legs.

Yup, she has changed a lot since their childhood though she was still...flat in some parts, she was still very attractive in everything. She used to look like a small cute defenseless animal when they were kids but now she had grown into such a lovely girl.

"Are you checking me out?" Len quickly looked up to see Rin scowling at him, a disgusted expression on her face. He grinned. "Maybe I am, by the way has anyone told you how beautiful you look?"

Rin rolled her eyes and continued eating her apple. Len sighed, sometimes he wondered about this girl. Was she ignoring it or was she just clueless to his feelings? Obviously she was the only girl who hasn't fallen for him. He- dare say- he had fallen for her instead of the other way around.

It was probably cliche but it definitely wasn't an everyday romance thing.

"Hey playboy! Let's go before I leave you here!" Rin yelled from outside, cutting into Len's musing. He was so deep in thought that he didn't notice her leaving the kitchen and to the front door a few minutes. He grabbed his bag and ran outside where she waited.

Well...sort of, since she was already a few blocks away.

"Wait up!" He called, chasing after her. When he reached her side, Rin walked away faster while Len kept up with her easily. After a few minutes they arrived at the school.

The first thing that happened as soon as they reached the gate of the school was a girl crying out. "It's Len Kagamine!" Then a group of girls suddenly formed around Len, literally pushing Rin at the sides. She sighed as walked away from them and towards the school.

Yup, it was going to be a very long day.
