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 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.

    I just wanted to share this link with you all. It has the chapters in order:

  2. not the best work from this author August 26, 2014 7:06 pm

    I really like to story but i didn't like Atsushi Arisawa at all, he is just to girly for me. everyone else is ok but I just can't stand that kid.

    I really like it so far and I really want to continue but until the pages are put into order I don't think I will continue. It's confusing and not at all fun if I can't understand how it's supposed to play out. It only really started to show up around volume 3 10-12 chapters. love it and hilarious but please have it in order sometime soon. It's getting really good and the art seems to improve as I go along so without a doubt I'll read it, just in order, and probably sometime later. I recommend it just be warned.

    loved it! woot! they become more handsome.. kyaa!! but i think the body proportions are kinda off... hehe

  9. Maidas January 28, 2014 6:17 am

    I really liked this one! Although I actually thought it'd be more focus on Ari and Ma-chan more, but oh well. Another thing is that I had a feeling that they both didn't have a strong connection or something? Lol that's what I'm feeling. It might be just me who thinks so. Don't mind me. ;"}

    Hate, sorry, definitely not something I'd read. Not trying to say that you guys shouldn't read it tho, just sayin'. /)._.(

  11. Kira August 17, 2013 11:23 pm

    At the End I cried so Much. This is the first manga where I've seen characters grow up so quickly and beautifully. I just love how they care for each other so much. I would recommend this to so many people. Oh, and I didn't read it on this site because the pages are messed up.

    that was different to what i normally read and i defiantly wasn't expecting the uke to be sensei....that one was shocking. still a good read though

    • ester March 24, 2013 2:59 am

      Ah you revealed the whole thing !

      I was reading the comments to know if it was a good manga and BAM : unwanted spoil u____u

      i forgive you but you kind of ruined the uke/seme suspens dude x)

  17. shirayuki April 19, 2012 2:35 am

    heck starting vol 3 the pages are just scrambled!!! what a mess

    • shirayuki April 19, 2012 2:58 pm

      still, i like this manga very much.
      i didn't think that Masa-sensei is going to look even younger in the end, though. haha

      I really wish to read this manga again, so someone, anyone, please do something about the unorganized pages!!! waaaahhh~!!

  18. cute March 23, 2012 5:49 am

  19. Sion January 22, 2012 1:59 am
