作品概要

Mika (a fudanshi in his previous life) is reborn into the world of a BL novel as a pathetic villain fated for certain death by execution. In order to avoid death, Mika decides to act as a mother-figure for his childhood friend Charles, the main character of the novel, to make sure he becomes a pure and innocent virgin boy. Thanks to his hard work, Charles grows up in a peaceful and healthy environment, but… “Baka Mika… one day I'm going to fuck you up.” Uh… what? Where did I go wrong? (Source: Gene Pixiv, translated)
