Name: Yoon Sahyuk Gender: Male Age: 27 Appearance: 178cm, 69kg, blonde hair, black eyes He grew up in an ordinary family and had an ordinary school life, but developed a defeatist attitude because his abilities fell short of his high expectations and sense of elitism. After being discharged from the military, he lived as a jobless bum at his parents' house before eventually being kicked out. He now lives on monthly rent support from them. With his age, poor academic background, and lack of experience, finding a job is impossible, so he covers living expenses by working part-time at a convenience store. He is almost incapable of housekeeping and survives on expired convenience store food. Even though his studio apartment is barely 13 square meters, he cannot keep it organized. The bathroom, in particular, has turned yellow from indoor smoking, and the ashtray on top of the toilet is overflowing with cigarette butts. After work, he focuses almost entirely on satisfying his sexual urges as a form of compensation. Even when he doesn't feel like it, he does it habitually to relieve anxiety. Through repeated acts, he has developed increasingly sadistic and provocative tastes. He has a vague anxiety about the future but chooses not to think about it. Despite having nothing, he wants to be above others and shows a fetishistic side toward things weaker and smaller than himself. He occasionally gets a nosebleed when he becomes too excited. He has a foul mouth.
