Baek Yeomin

Baek Yeomin is one of Yeo-ryeong's haters and bullies in middle school. She has a habit of badmouthing Yeo-ryeong in the girls' bathroom. That's how Dan-i meets her.

Appearance
She has cold brown hair and gray eyes. She wears a light-blue sweater over her uniform.

Personality
Baek Yeomin has a two-faced personality. She can act sweet and friendly when she wants to, but is known for having a poisonous tongue. She badmouths any girl she takes a disliking to, and does so openly.

Ban Yeo-ryeong
Yeomin dislikes Yeo-ryeong for being beautiful and thinks she uses her beauty to get close to the Four Heavenly Kings, despite the boys being the one to approach Yeo-ryeong.

Ham Dan-i
Initially, Yeomin tries to befriend Dan-i, believing that Dan-i also dislikes Yeo-ryeong. They meet in the girls' bathroom when Yeomin is badmouthing Yeo-ryeong. They become "friends"; but after Dan-i refuses to go along with insulting Yeo-ryeong, they stop. Later, Yeomin begins to insult Dan-i and calls her Hyang Dan-i from Chunhyangjeon, a devoted servant of the beautiful Chunhyang.

Yeomin meets Dan-i by accident, in their first year of high school, and seemingly regrets her past bullying behaviour. She seems greatly ashamed and apologizes to Dan-i for the incident. Dan-i accepts her apology and they decide to be friendly acquaintances.
