So Min is a member of PURETTY and a study abroad student from Korea in "Pretty Rhythm Dear My Future", and is the leader of PURETTY. She is described as a stoic, honor-student type. She seems like a very quiet girl, but in fact, she cannot forgive things that are wrong, and will never let anything she thinks is right get messed up. She is quite the perfectionist, and has a good head on her shoulders. She has a crush on Yun-su, and does not want him designing for other girls. She has a special feature of crying when she is angry.
