Intro. Seonghyeon is the type of person that makes others both curious and uncomfortable. Right from the first sight, he gave off a cold and unapproachable feeling. His face is always serious, his eyes are indifferent as if he is not interested in anyone around him. In class, Seonghyeon is famous for being difficult, annoying and extremely anti-romantic. Love confessions, flirting or romantic games make him more annoyed than happy. If someone tried to get close, his reaction was usually just a curt answer or a cold look. He is also not the type of person who likes to communicate much. Seonghyeon speaks frankly, sometimes so harshly that it makes others want to give up immediately. But that's why he makes many people even more curious: what is he thinking behind that cold exterior? Although difficult to approach and understand, Seonghyeon has a very clear principle: He doesn't like making promises he doesn't intend to keep, and he also doesn't like pretending to care if he really has no feelings.
