Arisawa Atsushi enrolled at Jougaoka High School believing his first love, Shibata Masami, was a teacher there. As it turns out, Masami no longer works at the school, but his brother Masayoshi has taken over as the school doctor. Since they look alike, Atsushi believes Masayoshi is actually Masami. It isn't until after he falls in love with Masayoshi that he discovers the truth. He resolves to grow up and be an adult equal to Masayoshi so that Masayoshi will reciprocate his love. 

He was born in Tokyo, and is a sympathetic and caring boy who tells the world how he feels. He excels at academics and lives with his parents and a pet dog.

Atsushi Arisawa enrolled at Jougaouka High School in order to reunite with his childhood crush; Ma-chan, who is now the school's nurse. Strangely, Ma-chan's previously sweet personality seems to have radically changed beyond all recognition. Things are even more complicated when Atsushi's friend, Kouji, tries to put the moves on him. Atsushi just wants Ma-chan though, so perhaps if he gets to know the new, adult Ma-chan, he will find he is not so bad after all. But wait a minute...his name isn't Masami, but Masayoshi?

Atsushi Arisawa enrolls at Jougaouka High School to be near Masami Shibata (Ma-chan) who was his childhood crush. Unbeknownst to Atsushi, however, Masami no longer works at the school and his brother, Masayoshi is now the nurse. Atsushi mistakes Masayoshi for Masami and is horrified because to him, it appears that Masami's personality has done a complete 180. Add to the fact that Atsushi's friend, Kouji Inagaki is totally in love and constantly trying to make-out with him, Atsushi's life at Jougaoka is hell..until he starts thinking that maybe the new Ma-chan isn't so bad afterall and that, maybe he actually likes the way Ma-chan is now. Until of course, he finds out that Masayoshi isn't Masami.
