Juyong Gong

공 주용

Neighbor of Hong Seol when she was living alone. He has an old bond with Yu Jung. [Spoiler] He is actually from a very rich family compatible with Yu Jung but leaves them when they do not approve of his relationship with Yunseob. In the end, he goes back to his family when he gets accused for stealing underwear (even though he did not steal them). [/Spoiler]
