OH MY LORDY. YOU HAVE TO CONTINUE THIS. AND SOON. PLEASE. IM BEGGING YOU.

I like the general idea of the story(I love high school AU) but some things seems a little fast here: First how did zoro knew where sanji was living (when sanji was being healed by zeff)? Is he sanji's neighbours? Is he living alone ? Since when is he sanjis friend?(you cant enter someone's house without knowing the person a little.) maybe you wanted to put an ellipse of time but if its the case we don't really understand:first we read that zoro is a new classmate,sanji looks like he doesn't care,he is hurt by baggy and the next evening zoro enter in his house just like that?or maybe it was at the high school(that would explain why chopper and doctorine were here)?and why ,from the same evening zoro and sanji are "sleeping" together as if they were long time friends and zeff just doesn't remarks it. And last question,is sanji bi? Because he doesn't seems bothered by holding a man's hand or liking a man even though the first line of the first chapter he is doing one night stand with women.
All these remarks are here just to help you writing a better story because your idea seems really good ! I'm not an excellent writers too but I do read a lot of story and I rarely criticize something I just suggest ideas for you to use :D.
Anyways I love the thug but smart sanji with an evil ace with him(I love acesan as well as zosan) and I cant wait to read the continuation :)
Continue like this and courage for the next chapters
