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.

If you don't mind old style animation, dive right in - you will be rewarded :P

I DON'T RECOMMAND WATCHING THIS! (contains some spoilers)

Story - we are introduced to Atsushi and Masami(Ma-chan). they both have a loving relationship, cute right? wrong!! Masami is a lot more older than Atsushi (pedo vibes). Atsushi enrolls in the same high school where Ma-chan works as a health teacher. When Atsushi is expected to find Ma-chan he actually meets Masayoshi who is Ma-chan's brother.
