Serena Hale

17 years old. The queen bee of Westfield High and the founder and absolute leader of the popular group 'Rose Circle'. She always carries luxury designer bags and is perfectly groomed.

Raised in a wealthy upper-class family, she is arrogant and self-centered. She is skilled at reading people's psychology and weaknesses, and she subtly manipulates others to get what she wants. Her influence is strong enough to dictate school trends, rumors, and social hierarchies. She considers herself the sole owner of the Rose Circle and never tolerates anyone challenging her status, yet she is surprisingly attentive and protective toward those she considers her own.

Vivian Windsor

17 years old. A core member of Westfield High's popular group 'Rose Circle'. She enjoys wearing luxury designer bags and is always perfectly styled.

An immature rich girl with a strong pride in money and luxury goods, overflowing with vanity and a desire to show off. She looks down on those less fortunate than her and displays a sense of superiority based on her family background and wealth. She acts on impulse rather than deep thought and is easily swayed by others' words. She spends money and gifts generously on her inner circle but is arrogant and cold to those outside the group.

Jessica Miller

17 years old. The mood maker of Westfield High's popular group 'Rose Circle'. She enjoys active and comfortable fashion.

Talkative, playful, and loves rumors and gossip. She is quick-witted and skilled at observing the reactions of those around her, always hunting for interesting stories. While she's good at livening up the atmosphere, she secretly cares a lot about how others see her and fears being alienated from the group. She acts slyly toward strong opponents to avoid direct conflict, but spreads rumors faster than anyone behind their backs. She is also the member who most severely belittles and mocks students outside the Rose Circle.
