Choi Yuri

Choi Yuri is a girl from Ban Yeo-ryeong's class in high school, Class 1-1. Yeo-ryeong befriends her because she vaguely looks like and reminds her of Ham Dan-i. She is the only daughter of the CEO of Yoosung Enterprise.

Appearance
Choi Yuri has short bobbed hair like Dan-i, but her colouring is cooler. She wears two hair-clips above her ears.

Personality
As one of the villain characters, Yuri is two-faced. She pretends to be sweet, humble and caring - apparently emulating how she sees Dan-i. Despite her behaviour, her words are often manipulative and pointed. She manipulates mostly by gaslighting or instigating doubt. Yuri also uses her wealth to create problems for her victims.

It is implied that Yuri smokes cigarettes (Dan-i smells it on her in Ch. 81) - a direct contradiction to her "sweet girl" image.

Ban Yeoryeong
Choi Yuri is introduced in the story as Yeo-ryeong's only friend (other than the Kings) from Class 1-1. She is seemingly very sweet and kind to Yeo-ryeong, but secretly despises and envies her for being beautiful and "surrounded" by the Kings. On multiple occasions, it is implied that Yuri masterminds harassment incidents to trouble Yeo-ryeong. She befriends her to (a) find a way to become close to Eun Ji-ho and (b) destroy Yeo-ryeong's and Dan-i's relationships with the boys.

Eun Ji-ho
Choi Yuri met Ji-ho at a party 2 years before the start of the webtoon. The party was to celebrate the 20th anniversary of Haneul Group. Ji-ho and Yuri were apparently meant to form a political marriage, but Yuri fell for Ji-ho. Her infatuation fuels her jealousy of Yeo-ryeong and Dan-i. She overhears Ji-ho confessing to Chun-young (Ch. 76) that he had feelings for Ham Dan-i in middle school and decides to "get rid of her".

Ham Dan-i
Choi Yuri targets Dan-i as her rival: she sets up an anti-fan cafe in order to frame Dan-i and distance her from Yeo-ryeong, and eventually force her to transfer schools. Dan-i is the only person in front of whom Yuri never continues the sweet girl image; this is probably because she doesn't see Dan-i as a threat at all, ability-wise.
