Homeroom teacher Takumi Kubomura is having a hard time dealing with Konagi Irie, a cheerful female student that is utterly smitten with him. Both are utterly clueless: Takumi with Konagi's feelings for him and Konagi with Takumi's job as a teacher that she believes is him trying to spend time together with her. When he overhears Akkun saying mean things to Nontan despite them being dating, he questions Akkun about his feelings for his girlfriend, which are that of a pure-hearted young love. Wishing to understand and educate his students, he requests that Akkun say mean things to him in hopes of putting himself into Nontan's shoes.
