About this title

Synopsis

Arisawa Atsushi enrolls at Jougaouka High School to be near Shibata Masami (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, Inagaki Kouji, 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 after all, and that maybe he actually likes the way Ma-chan is now. Until, of course, he finds out that Masayoshi isn't Masami. - AnimeNewsNetwork

External profile
Shibata Masayoshi works at Jougaoka High School as the school doctor and occasional substitute teacher. Outside of Jougaoka, he works as the owner of a gay bar that his father used to run, although it&#039;s really in his older brother, Masami&#039;s, name. He&#039;s loud and abrasive on the outside, but he is actually a very insecure person. He&#039;s confused by Arisawa Atsushi&#039;s behaviour toward him until Atsushi accidentally drops a picture of himself and Masayoshi&#039;s older brother, and realizes Atsushi has mistaken him for Masami. His and Masami&#039;s father is Japanese, while their mother, who died when the brothers were young, was Norwegian. Their father lives in Norway with their grandmother, while the brothers live together in Japan. (Written by Toadychan)
