So the story goes in this world there is a phenomenon that could happen if a daughter is living with their father / fall in love with their father so hard that the body would change the DNA to avoid incest(?) making the daughter essentially compatible with their father. It was called like a syndrome I think. In this world it is legel to have sex with your daughter who has this syndrome but you do get looked down upon by close relatives (it was mentioned several times). The story was like a compilation of this phenomenon where the girls would get tested for the syndrome, confessed to their father, and they had sex. Can’t really go into detail into each couple but I remember one of the couple is that after their mother died, the father worked hard and became like a successul CEO or something like that.
Anyway TQ in advance.
