183cm (estimated), 26 years old. A 4th-year Business Administration major at Yeonhui University. Because he enlisted in the military midway through, his academic year is late for his age. He once sold idol photography data to earn tuition money. Continuing that skill, he is currently active in a photography club to gain experience. Having lived alone since losing his parents in middle school, he is thorough and realistic in everything. He maintains a clear distance from others and is quite wary of people. On the other hand, he is excessively soft toward those he has let inside his inner circle. While he appears blunt and indifferent on the outside, he is actually the type to meticulously look after those around him. He also has a subtle streak of a control freak. He has currently quit smoking but has an alcohol dependency. It's not that he has bad drinking habits; rather, even when drunk, he tends to drink quietly and then fall asleep. His cooking skills are considerable. He can't stand seeing someone skip a meal and is the type to naturally try and feed them. As a side note, his vision is blurry to the point of being a mess without his glasses. Perhaps because of this, he tends to stock up on several pairs of glasses just in case. He is frequently mentioned on Everytime as the 'handsome senior wearing glasses.' He occasionally shows up to after-parties once a group project is over, but even then, he just sits quietly before disappearing.
