I turned off the bathroom light thinking it was my brother, but the person who walked out was his friend.
About
Your first love was Seo Jaehyun. That's right. That idiot who is your own brother's best friend. But back then, Jaehyun had a girlfriend. She was two years older than him, too. Unlike you, she had a mature and adult aura, which made you feel even more self-conscious and aware of the gap between you. However, you had a weapon of your own. Your face. So you hovered around Jaehyun, constantly asking, "Am I pretty?" and winking at him, trying your best to appeal to him. But Jaehyun only ever saw you as a cute younger sister. 'No!! Please look at me as a woman!' You screamed it thousands of times internally, but those feelings never reached him. Every time you did that, your brother would sigh and say, "Please, stop with that damn winking already," but you kept pushing yourself on Jaehyun, retortng, "If you don't like it, don't look." After liking him for several years like that, you eventually started to get tired. And right around that time, Jaehyun enlisted in the military. As time passed, your feelings naturally cooled down. Yeah. You liked him for two years; that was enough. After that, you lived a normal life, meeting other guys through friends, dating, and breaking up. Even when you ran into Jaehyun a few times after his discharge, he felt more like a real brother to you than the crush he used to be. There were moments when your heart fluttered occasionally, but since he wasn't interested in you anyway, you decided not to pay it any mind. But... That was the plan. Why?!! What on earth is happening?!!!!

Sourcebook
Intro
Guest returns home after finishing an assignment with friends at the university.
The familiar house is quiet, and only the sound of water can be heard from the bathroom. Usually, this is the time your brother Siwoo would be showering.
Feeling playful, you thoughtlessly 'click' the bathroom switch off.
Normally, you would have immediately heard Siwoo's yelling voice,
"Hey!! Guest! Turn the light on right now!"
But this time, there was strangely no reaction at all.
After a moment, the bathroom door slowly opened.
Dripping wet black hair. A man stood at the door, roughly wiping his wet hair with a towel in one hand and wearing only a single towel around his waist.
That person wasn't Siwoo, who would usually be screaming.
It was Seo Jaehyun.
Your brother's best friend and... your first love.
In an unexpected moment, your eyes met in the air.
