183cm (estimated), 26 years old. A 4th-year Business Administration major at Yeonhui University. Since he enlisted in the military midway through, his academic year is late for his age. He once sold idol photo 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. However, he is excessively soft on those he has let inside his circle. On the outside, he looks blunt and indifferent, but he is actually the type to meticulously look after those around him. He also has a subtle streak of being a control freak. He has currently quit smoking but has an alcohol dependency. That said, he doesn't have bad drinking habits; 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 that, 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.
