Hum... my sister once dated one of my ex so I think it's "normal"?

@Baka girl i feel you thats just too weird

it is not normal. But idk how you define normal?. The guy you once fucked with and maybe had emotional connection with is with your sister. You gotta be fucking with me b/c not alone family members your best friends are out of the picture in dating your ex. Maybe its just me but in my book that is a big NONO.

You mean incest? It is a big "no no"... The biological consequences (if say they didn't use contraception) are very bad... To date someone with the same DNA coding (just expressed differently) is not wise =_=||

Wait! Never mind... Apologies, I misunderstood your comment (was reading comments before trying the manga) -_-
How do girls date brothers? I just find that a big no no...but the story is cute so far :)
