Mitsu is a high school girl hiding a secret crush on Ryuuzaki, the most popular boy in her class. To protect her feelings and avoid humiliation, she constantly acts like she cannot stand him, putting on a show of dislike whenever they interact. Beneath this prickly facade, she longs to be closer to him than anyone else. Ryuuzaki routinely teases and provokes Mitsu, keeping her off balance. One day, he suddenly kisses her, leaving Mitsu reeling with confusion and doubt. She cannot tell whether the kiss is a genuine expression of interest or just another one of his playful taunts. Torn between hope and anxiety, she makes a desperate decision and blurts out a confession to him, setting off a chain of reactions that test both of their true intentions. Set in a contemporary Japanese high school, the story follows Mitsu and Ryuuzaki as they navigate the tension between pretense and honesty. The manga unfolds as a self-contained, single-volume romance that centers on the push-and-pull dynamic of a tsundere-style relationship, exploring themes of vulnerability, miscommunication, and the gap between how the characters act and what they truly feel. The main narrative arc covers Mitsu's internal struggle, Ryuuzaki's ambiguous behavior, and the fallout from her impulsive confession, building toward a resolution of their unresolved attraction.
