In the first year of high school, there was a girl that caught the attention of a student named Takemitsu Saeki. The girl’s name was Sanae Kashiwagi. They had been friends since infancy, commonly known as childhood friends. Encouraged by the advice of his friends, Saeki decided to confess to her. However, she was already in a relationship with the handsome but notorious guy in their class, and Saeki was harshly rejected. In his despair, Saeki visited a nearby shrine to pray, where he encountered a suspicious old man who insisted he was a ‘god’. As thanks for the offering of money, the self-proclaimed god bestowed upon Saeki a magical item which will help in becoming popular with beautiful Yandere Girls. Although skeptical that it might be a top-tier cursed object rather than a magical item, Saeki, who wanted to win her over, gratefully accepted it. And then, through a series of unexpected events, he found himself being confessed to by an unbelievably beautiful girl.
