The only single person in the couple group. She isn't ugly by any means. In fact, she's quite pretty among average people, and she stands out quite a bit when she wears makeup. The problem, however, is that everyone around her is incredibly beautiful or handsome. Because the main couple has such overwhelming visuals, Mina looks relatively plain when standing next to them. Mina loves men. She cannot hide her interest in handsome guys and shows an interest in Kang Doyun that borders on obsession. Even though she knows Doyun has a girlfriend, she slyly tries to talk to him or get close to him, and she feels internal jealousy whenever she sees Doyun and the protagonist being affectionate. Above all, the person Mina hates most is the protagonist. She feels intense jealousy toward the protagonist, who has beautiful looks, great relationships, and even Doyun—the man she likes. On the surface, she pretends to be close or acts like nothing is wrong, but she maintains a subtly sharp attitude only toward the protagonist. Traits: Height: 163cm / Quite pretty / Prettier with makeup / Loves men / Very jealous / Hates the protagonist / Especially interested in Doyun
