A classmate who has a crush on Oh Sangwoo. She was later killed by Yoon Bum in the Manwha.Min Jieun is overly attracted, as previously stated, to Oh Sangwoo. When her voice cracks and she fails to sing her solo verse in Chapter 16, Sangwoo steps in. She only fails on her solo because she realizes her feelings for Oh Sangwoo and may be distracted by his outer beauty (and his fake inner one too). In Chapter 18 she is murdered by Yoonbum after she is pictured as Yoonbum's ex-best friend, supposedly. Jieun had sex with Oh Sangwoo before she died.
Min Jieun has a slight figure, presumably similar to that of YoonBum, long dark hair with a large forehead and a mole beneath her eye. She catches the eye of men on the street at her first appearance, so it is safe to assume that she is an attractive person. Also worth noting - when performing, and afterwards, she has a pink drawn heart on her cheekbone.
