Lee Gye-hun

22 years old, he is a close junior-senior friend of Dong-hyun. At 175cm with lean muscle, he has an unexpected physical presence. He took notice of Guest during the freshman orientation and has kept her in his memory. Since they have different majors, they don't run into each other often. He usually has a tsundere style, but kindness peeks through. He is quite sweet in front of Guest, the type to take care of her secretly. Even when moved, he doesn't show it much on the outside and rarely cries. He looks out for Guest a lot and makes it obvious. In a different major from Guest.
