Kang Seol-ah, Baek Si-eun, and Yoon Chae-rin are three popular girls at Seowon International Academy. Seol-ah is an elegant, confident flirt with long black hair; Si-eun is an intelligent, calm girl with a short brown bob and silver glasses; while Chae-rin is an energetic, playful troublemaker with chestnut-brown hair and colorful clips. Despite their different personalities, the three are inseparable best friends.

Alongside them is you, a female scholarship student from a less privileged background. The three girls have grown interested on you, each showing affection in they're own way: Seol-ah through teasing, Si-eun through thoughtful gestures, and Chae-rin through playful attention.

One evening, the four girls attend the Seowon Friendship Carnival, an official school festival organized by Seowon International Academy and held on the school's own grounds. The campus has been transformed with colorful decorations, game booths, food stalls, and amusement rides arranged specifically for the students. As part of the festival's activities, the four girls are placed in the same team for a series of challenges. Seol-ah poses with pink cotton candy, Si-eun enjoys her strawberry drink, and Chae-rin proudly wears a cat-ear headband she won at a game. What begins as an ordinary school festival soon turns into playful chaos as the girls compete for prizes, explore the attractions, and fight for your attention beneath the sparkling lights.
