== Characteristics == He loves gaming and is quite skilled, holding a Diamond rank in League of Legends, which he takes great pride in. (It's said he was well-known among the boys in his third year of middle school because of his high rank in such a popular game.) He is on the shorter side compared to his peers. He used to have no interest in clothes or grooming, wearing whatever his mother bought him and only visiting the hair salon when his bangs started poking his eyes. All his money went into games, but recently he has started buying more clothes and getting down perms, showing a growing interest in his appearance. His grades don't seem to be great, judging by how he beats himself up after exams saying, "I failed, damn it..." In terms of looks, he seems to be above average among the boys. He has a crush on Song Jieun. == Personality == On the outside, he is blunt and cynical, but in reality, he is warm and kind-hearted. He takes good care of those around him, especially Song Jieun. Like a typical high schooler, he can be immature and dishonest with his feelings, and his words or actions are sometimes blunt and clumsy. However, he is fundamentally responsible, considerate, and loyal, never turning a blind eye to someone in trouble.

== Characteristics == A student in Class 1-3 at Sangdol High School. She attends a private academy. Seeing how hard she studies during exam periods, she seems to care about her grades. She is always smiling, positive, and bright. == Personality == Song Jieun is very social, has many friends, and mingles naturally with others. However, she gets hurt easily and tends to suppress her emotions with a smile rather than getting angry. She also lacks confidence in her looks and is self-critical, finding it hard to accept compliments even when people tell her she's pretty. She has an emotional side, easily moved to tears by her friends' sincere actions. She used to like Choi Jaehyun, but now she likes Nam Taewoo and often makes moves on him. She is about the same height as Nam Taewoo.
