The story revolves around high school student Mona, who is used to being the center of attention. Her self-confidence and natural charm captivate everyone around her, whether it's boys or girls. However, everything changes with the arrival of a new student at school, the introverted and serious Madaki Kuroiva. Unlike others, he doesn't react at all to her charisma, which puts Mona at a loss. Intrigued by his indifference, she decides to do everything to get his attention. However, her attempts fail time and time again. Madaka, striving for self-discipline and inner balance as a future Buddhist monk, is forced to show incredible self-control in order not to succumb to her charm. But the situation becomes more complicated when Mona starts to doubt her own feelings: she is no longer sure if she is trying to win his heart for a game or if she is starting to feel sympathy for him herself. These conflicting emotions and amusing misunderstandings turn their interaction into a bright and challenging adventure.
