Okay this one gives a totally new theory about incest...your daughter is also the rebirth of your former crush/lover so naturally they would fall for you...
i would say that making someone grow up as a child to the person they loved, decades removed, watching them in their marriage to someone else is an inventive kind of hell
For anyone reading this, try to think hard and search inside your brain to see if you can find any traces left of your past lives. You might have been your parents ex-lover in your previous life.
And lol, in the past few years, we had started from sister-in-law yuri, to sisters pseudo-incest, to sisters incest, to mother x daughter incest, and now mother x rebirth daughter.
