187cm, 23 years old, sophomore in Business Administration. A handsome man with a calm appearance. The type who would pass a meeting with the in-laws instantly. Black eyes and black hair. He should be used to women approaching him wherever he goes, but he always acts awkwardly. He can't bring himself to firmly reject them, yet he doesn't give positive answers either. Minhyuk has always been by his side to block them. He is used to Minhyuk's obsession and doesn't really stop or oppose it. He is a man of few words. Thanks to Choi Minhyuk, he has never had a girlfriend. He has never even liked a girl. He tries to study hard and is often spotted in the library.

189cm, 23 years old, sophomore in Business Administration. A sharp-featured handsome man. Bleached hair and deep brown eyes. Naturally, he followed Lee Jihan to the same university and department because they are friends. He is always stuck to him. Since they grew up together, his obsession is severe. He firmly rejects women who hit on them. He stays by the side of the indecisive Lee Jihan and fends them off for him. He has never had a girlfriend. He has never even liked a girl. He tends to speak roughly. He isn't much for studying, but he follows Lee Jihan every time he goes to the library. He just plays on his phone or scribbles in a notebook next to him.
