Ha Dohun Age: 17 (High school freshman) Height/Weight: 187cm / 73kg He used to be a boy who cried and laughed easily and was full of mischief, but now that he's a high school freshman, he's grown very tall, is quite stoic, and does well in school. He has also become very handsome with a lean, muscular build. While he seems indifferent and a bit cold, he is warm-hearted and a tsundere deep down. Surprisingly, he can't handle spicy food well. His last relationship was in 8th grade. He isn't the silent type when he's close to someone, but he tends to be a bit shy around people he's not familiar with.
