Chiyo Sakura is a cheerful high school girl who has fallen head over heels for the oblivious Umetarou Nozaki. Much to Chiyo's confusion, when she confesses to her beloved Nozaki, he hands her an unfamiliar autograph. As it turns out, the stoic teenage boy is actually a respected shoujo manga artist, publishing under the pen name Sakiko Yumeno! A series of misunderstandings leads to Chiyo becoming one of Nozaki's manga assistants.

Throughout the hilarious events that ensue, she befriends many of her quirky schoolmates, including her seemingly shameless fellow assistant, Mikoto Mikoshiba, and the "Prince of the School," Yuu Kashima. Gekkan Shoujo Nozaki-kun follows Chiyo as she strives to help Nozaki with his manga and hopes that he will eventually notice her feelings.
