I think I read up to vol... 5? I stopped around the part where the guy who likes Yamada returns through his "extensive training" in order to get rid of the feelings he had for Yamada but it all that hard work went poofles when he saw Yamada LOL~

I was hoping for more of Yamada and his close friend who knows that he's poor but apparently he's a player and already is engage to a loli.
