Let's get start. The mc is the father of the yandere boy(black hair child) in the original story. Or rather, the person who gave birth to it. In the original story, our omega Mc committed suicide. That's why the little boy developed an obsession with the psychiatrist's son(cute baby) because he resembled his father(our Mc). They both have brown hair and eyes. But now the father(our Mc) did not commit suicide. This will change the original story.

Oohh lol I see, thanks for clearing that for me. I was wondering why each child resembled the other fathers rather than their own, but it’s for the story plot. So that MiL is the kids grandma. Plot wise in the original story, mc should be dead by then, but psychiatrist saved him. But other than the original plot of their children getting together, they have no formal relationship or ties to one another right?
I get that the guy is now a character in his sisters story, but I’m confused on who he is and his relationship with everyone (don’t get me started on the names, it’s so hard for me to remember who is who, even with American names)
