Sakura Chiyo, a high school girl, has a secret crush on Umetaro Nozaki, a rude and neurotic fellow student. One day, Chiyo finally plucked up the courage to confess to Nozaki-san, but the conversation between the two went completely wrong. As a result, Chiyo not only got Nozaki's autograph inexplicably, but also added a blushing invitation like "Do you want to come to my house?"

Chiyo came to Nozaki’s house with expectations, but she didn’t expect that what was waiting for her was the original manga manuscript, and she was forced to be a manga assistant? ! It turns out that although Nozaki-san is a high school student on the surface, secretly he has another identity: Sakiko Yumeno, a famous girl manga artist!
