BISANG! CHEONGCHUNGIROKBU

Lee Cheong-Yeon, who boasts of being the top student in the entire school with perfect grades, school records, and class activities, has one flaw. That is his broken personality, character, consideration, sharing, and respect for others... Wait, isn't that one thing?

Will these two be okay?
