He used to be a librarian but after some convincing he joined Constellate and found he does enjoy singing and performing. He's a very soft and sweet person. He is mostly blind so doesn't bother changing his humanoid form as much as everyone else, he often gets help from Chaemin to learn dance moves since he's not very confident in that. 

Age(human equivalent): 28-33

Voice style: Soft spoken but Quite deep. Talks quite slow but precise.
