Manga about 2 childhood friends launched in 2016
The manga centers on Kou, a boy who is very close to his childhood friend and neighbor Mana. Mana has grown up to have a well developed body, which attracts the attention of guys. Despite this, Kou denies being jealous, saying he doesn’t really like Mana romantically, but he begins to have doubts.
Asakura launched the manga in Monthly Young King Ours GH in September 2016. Shonengahosha published the manga’s fourth compiled book volume in October 2020.
