The Perks of Being Gumball (gumlee)

Barnaby Gumball Candy was new, frightened and quiet. He watched what went on around him but it never crossed his mind about putting his life first. After moving to his new school he meets a couple people who were going to change his life; Cake and Fiona Mertens, a pair of mischievous sisters, Flame Princely, a hot headed know it all, Mono Chromium, a quiet goth boy with a big brain and Marshall Lee Abadeer, who's mind only knew two things, obscure rock bands and being to bad for his own good.Together, they're going to flip his life upside down.

(This is based slightly on The Perks of Being a Wallflower, but I am going to try and stay away from copying the story line completely, characters are also not mine but I wish they were, as the title also say this is a gumlee story but there will be side ships as well)
