Tanaka is a socially awkward, unattractive male student. He has no romantic feelings for women, seeing them merely as an outlet for his sexual desires. His excessive sexual desires are unusual and perverse, but he's not even ashamed of it. One day, he receives a message from someone who suddenly added him to his friends list on LINE, which he uses to keep his family in touch, asking him to be a tester for a hypnotizing app. His life changes completely from that day on. Tanaka's homeroom teacher is beautiful, but she has a harsh personality and tends to get everyone angry with her. She also has a deep dislike for Tanaka and goes too far in her teaching. To Tanaka, it's not painful. But more than that, why is she able to unilaterally vent her feelings on him? Perhaps her overbearing attitude is also a way to hide her true feelings. Ah, that's right. It's times like these that remind him of something useful. Having incurred the wrath of Mr. Tenma, Tanaka is left standing in the hallway with a grin on his face. This is the very moment he begins to create his own story...
