hey wanna go out with me my childhood friend a beautiful girl asked me to be her boyfriend and ive started a camouflage boyfriend

childhood pals masaichi mazono, an otaku lad, and toiro kurumi, the most gorgeous girl in school. toiro was meant to be like family to masaichi because he was always in his room. toiro, who was getting tired of her romantic problems, begs masaichi to assume the part of her boyfriend one day. because they’d been together for so long, they thought it would be easy to pretend to be a couple, but their ideal childhood pal can’t possibly end up as a phony lover… “e-eh no, holding hands is embarrassing.” a childhood buddy who is more than a lover sets out on an adventure she could never have imagined!
