Gyuri didn't know when that became an habit — a settled or regular tendency or practice, especially one that is hard to give up.

Yet there she was, watching the short haired girl as her legs swayed back and forth as she sat comfortably at the edge of the school's rooftop, sipping on her favorite orange juice as if she wasn't meters away from the ground. Yes, she would be dead scared of doing this a month ago, but a month ago the brown haired girl wasn't a student in her school yet. Being able to contemplate such beauty everyday turned the fact that she could fall down, break her bones and maybe even die in just a simple consequence that, as she got more and more lost into the mysterious girl, Gyuri easily learned to ignore. 

There was this undeniably strong aura around the girl Gyuri have been watching for a whole month. She's always alone, rarely ever smiles and was always seen wearing her earphones as she reads some book under one of the many trees that there were in their school. The fact that their uniform was black helped building the whole mysterious vibe that the girl showed off since the first day she put her feet on that place, leaving Gyuri even more intrigued. She didn't know why or how she got so invested into the girl, but it just felt right. That's why she didn't — and felt like she couldn't — stop coming to the rooftop everyday ever since, and it was not like she was planning to stop anytime soon. 

Above everything, she felt like the girl was not only alone all the time, but that she was lonely. She couldn't see her face that clearly from where she would always sit, but she could still catch the glimpses of sadness that would appear every once in a while on the girl's sharp eyes. It reminded Gyuri of herself, and it made her chest hurt, because such pretty face and such pretty eyes should never be covered by unhappiness. And as much as Gyuri wanted to get closer to the girl, she knew nothing about her besides her name. She didn't know if she was a good or a bad person, she didn't know if she was open for a new friendship or not. All she knew was that she was beautiful, and as much as it hurt her it made her feel at ease at the same time, because at least she could still come to the same dangerous spot everyday and watch her from afar, silently hoping that one day they would be able to talk to each other.

One week had passed.

Gyuri asked permission to get out of the class so she could go to the bathroom, but she wasn't expecting to be received with such a scene as soon as she got out of the girl's toilet. 

There was the girl she would always watch at lunch, holding a boy by his throat as he did his best to get out of her grip and get some air, as two small girls watched the scene with wide eyes from the side. Gyuri recognized them, they were Jiwon and Jisun, two nice juniors who were in a secret relationship, which only Gyuri knew about. She shouldn't know, though, but a few months ago she walked into the bathroom when the both of them were kissing and almost made them cry of fear. Of course she would never tell anyone about that, but she begged the two girls to be more careful because god knows what could've happened if it was any other person. She wondered if the fight had to with that fact, but as she saw Jiwon holding Jisun close to her as her eyes were full of anger, she knew that stupid boy had done something to one of them. 

Gyuri couldn't even blink before the principal showed up and separated the fight, making the boy fall down on the cold ground as the girl's hands finally set him free. The girl's eyes were burning with rage, and she looked like she could and would kill the boy if she had the chance to. That's when Gyuri could finally see the red mark on Jisun's pulse and everything started to make sense. , she thought as irritation started building up on her too, getting even stronger as she heard the principal saying that the short haired girl would be going to detention for what she did. She stood up for a innocent girl and she's going to detention? Gyuri couldn't believe her ears. That was just what she needed to reach the edge of fury and for her brain to stop working properly, and the next thing she knew her legs were working on their own, running from the bathroom door until she was just in front of the boy, closing her hands in a perfect fist before hitting his stomach with a strength she didn't even know she had until that moment. 

To say that everyone was shocked was an understandment. Gyuri had always been a calm girl who never got into problems, much less a fight where she would punch someone. She was only brought back to reality when she heard the boy groan in pain as he came back to the ground, a smirk taking over her lips as she enjoyed the scene in front of her, looking straight into the principal's eyes as she waited for his statement. 

She got detention too, of course. And she couldn't even help to be bothered by it. Actually, the old man didn't know the favor he was doing to her. And when the girl turned around and smiled at her after they left the principal's room, Gyuri knew everything she did was worth it. That would sound weird in any other situation, but she couldn't wait for detention.

Soon all the classes of the day were done. Gyuri packed her things and left to the third floor, where the detention room was. She bumped into Jiwon and Jisun on her way, and the two younger girls couldn't stop thanking her for what she did earlier, or stop saying they where sorry for the fact that she got in trouble for it. Gyuri patted their shoulders and told them it was alright, and that she would do the same thing again if she had the chance. She couldn't help but feel a little jealous of the two girls as they walked away hand in hand, because even after all the bad things happen, they still had each other at the end of the day. And Gyuri, being the hopeless romantic that she was, even though she didn't like to admit that to herself, believed that true love could help you get through everything in life. 

She finally got into the room and groaned as she saw the two thick books above the table. She would have to finish the exercises of at least ten pages of each book before heading home, and she could feel her brain melt just at the thought of it. She took a sit and immediately let her head fall above one of the books, covering her face with her arms as she started regretting her actions. 

That feeling didn't last long, though. The door was open a few minutes after she sat down, revealing a slim figure with her earphones on, mindlessly throwing some strands of her hair over her head. There she was. Beautiful, breathtaking, alluring. Gyuri couldn't bring herself to take her eyes off of her. And she felt like the whole world stopped for a second when their eyes met, none of them daring to break the contact, allowing themselves to lose their breaths for a few moments. 

The girl didn't say hi, hello or any other type of greeting. She just left her backpack over one of the chairs before taking a sit beside Gyuri, who couldn't move a single muscle, or even turn around to face the other girl. Gyuri was trying to find anything to focus on that stupid room, but it was impossible as she felt that the girl's eyes were all over, and the more the time passed the more she felt that the awkward silence between them was becoming too much for her to take. 

"That was really cool of you. The punch, I mean." The short haired girl said, finally breaking the uncomfortable silence between the two of them, making Gyuri turn her head so she could face the other girl again. 

Gyuri was left dumbfounded this time. Lightheaded, dizzy. The girl's eyes shined so bright from this close that Gyuri felt like the other could easily read everything that was going through her mind at that moment. She also didn't expect the girl's voice to be this high and her speaking to be this slow, which only caused her to be even more curious about the girl sitting beside her. 

"Thank you, it was cool of you to stand up for them, too." Gyuri answered softly, almost as if she was scared of saying something wrong or end up stuttering in front of the prettiest human she has ever seen, which was true afterall, and Gyuri felt the need to punch herself in the face for sounding so small and fragile like that in front of her. 

She felt her stomach sink, in a surprisingly good way, when the girl smiled towards her again, the second time that day. Gyuri believed that it was the warmest smile someone has ever shown her, so sweet that it almost made her forget that they were on detention, with a pile of exercises waiting to be done. She smiled back and opened one of the books, furrowing her eyebrows as she realized it was a math book, her least favorite subject. Gyuri groaned and opened her notebook, getting herself mentally ready to go through that torture. 

The girl laughed a little bit before placing her hands above the blook and closing it, leaving Gyuri completely confused. That's when she took her cellphone out of pocket, put her password and scrolled a little bit through her camera roll before finding just what she needed. Gyuri's eyes went wide — the girl had the answers to basically every question in those books, and Gyuri couldn't help but wonder how she got them. 

"When the principal was talking to you in another room, I sneaked into his office and took pictures of all the answers in these books." She explained upon seeing Gyuri's reaction, and it only made the girl's eyes grow even more big. The brown haired girl couldn't help but laugh at Gyuri's
