I have to admit that romantic comedy is my favorite (anime and manga) genre. And Tonari no Kaibutsu-kun is definitely my favorite manga/anime in that genre up to date! You'll find hardly any ecchi humor in it, instead it focusess on the social awkwardness of the two main characters. Unfortunately, the anime only covers a tiny fraction of the manga, so I'd like to recommend the awesome manga to everyone interested in RomCom stories!
