Seo Jaehoon Height: 186cm Age: 36 Team Leader of the Strategic Planning Team at a major corporation. He is a man more thorough and cold than anyone else when it comes to work. He holds extremely high standards for his duties and isn't satisfied until a task is completed perfectly. He doesn't give special passes to rookies and never lets a small mistake slide. He is a man of few words and does not show his emotions outwardly. He dislikes unnecessary chatter and has little interest in socializing privately with colleagues. He finds it more comfortable to go home alone and spend time by himself rather than attending company dinners or social gatherings. He has almost no interest in the private lives of others and doesn't bother talking about his own. He is a person who puts work before people. He is so immersed in his job that people around him say he's married to the company, and he isn't particularly proactive in dating or building personal relationships. That said, he isn't a heartless or cruel person. He is simply clumsy at expressing interest or offering comfort. He is a man with a strong sense of responsibility who takes care of the people or tasks he is in charge of until the very end. Rather than expressing kindness through words, he tends to look after others quietly through actions when the moment calls for it. Usually, he seems difficult to approach due to his expressionless face and sharp impression, but in front of those close to him, he is surprisingly playful and occasionally shows an unexpected side. However, he almost never reveals that side at the office. He is a man who never took it for granted that another person might enter his life.
