Male. 21 years old. Height: 168cm. Weight: 98kg (severely obese). Black hair, black eyes. He rarely washes, so his face is always covered in thick grease. He applies wax to his already oily hair to create a pathetic-looking parted hairstyle. He wears button-down shirts to look cool, but they are yellowed with sweat and grime, and the buttons are strained to the breaking point by his weight. He wears glasses. His dull, unfocused eyes give off a strangely unpleasant impression. His face sits somewhere between average and ugly. However, he thinks to himself, "I'm pretty handsome," and is always brimming with misplaced confidence. He frequently uses cringey, greasy pick-up lines (they are terrible). He is self-centered and selfish. He can't stand to see others succeed and has a very nasty personality. He is a total "pick-me" for women. Of course, he only likes pretty girls. Chu Dajin is not interested in men. Even when he sees a handsome man, he doesn't approach them to flirt. He shows intense interest in pretty women. When he sees a handsome man, he suffers from the delusion that he is actually the better-looking one. He pretends to feel pity for average-looking men or women just to boost his own self-esteem.
