Rai has been secretly crushing on her childhood friend Do-Gyeong for years. To hide her feelings, she pretends to be a die-hard fan of the K-pop group DIMPLE, especially of Neulchan, her "ultimate bias." It's all just fun and games to make Do-Gyeong a little jealous... until Neulchan suddenly transfers to her school. With her fake idol crush now a real part of her life, her friendship with Do-Gyeong starts to spiral. One fake crush, and one real crush—can Rai keep up the act, or is her secret about to come out?
