Feel like fml got rapped or is a slut and dude's just her bitch. But I do know that there is a high chance the romance genre aspect in this one will be little and it's only good for fap material based on her previous works "Itokoi Chidori" and "Onna no Ko ga H-na Manga Egaicha Dame Desuka?".
It's not some high-school fantasy romance, where the girl is a inexperienced virign. It's more like a Chinese or Korean style manga that might or might not have NTR on it. Where the fml is kind of a slut that likes to fuck mc.
