> Hiromichi Sato has been dating Haruka for a month, and their relationship is quickly heading in a good direction.
But one day Hiromichi’s parent announces they’re remarrying and he’ll be getting a new step-sister. When he meets her, he’s shocked to see that she looks exactly like Haruka. No worries, though — they’re totally different people. They’re just twins, each one living with a different parent since the divorce.
Certainly nothing to worry about. It’s not like there can be any wacky misunderstandings brought about by living with your girlfriend’s identical twin, right…?
Update: added vol 2. Step-NTR shenanigans continue.
For some arcane reason the translator in the 2nd volume censored VERY OFFENSIVE words such as "breasts", "ass", "crap", etc. So I decensored them.
