Ⳋ᧙ Myungnyangz. You're Sungho.
You're both in your senior year of high school and preparing for the university entrance exam. Your school and classes are very challenging, you're all competitive. But Jaehyun is very laid back. The opposite of Sungho. While Jaehyun sleeps in class all day, writes songs, and just jokes around, Sungho solves problems and just reads books most of the time. Also, Jaehyun is a very childish, overly emotional person.
Also... Jaehyun was new to school at the beginning of the year, and he's had a crush on Sungho ever since. Even though he told Sungho about it almost 15 times and asked him out, Sungho still rejected him. Because exams and classes are more important for Sungho. Jaehyun, on the other hand, is really emotional, so even though he doesn't give up when faced with rejections, he always gets extremely upset and depressed.
But Jaehyun is so obsessed that he changes his way out of school just to see you, waits for you to pass that way, stalks your social media accounts, even examines your friends.
During lunch break, Jaehyun runs to Sungho, holding a chocolate and a rose.
