I would definitely not surprised that MC will become his own and his twin sister father, Kim's father, Chole's father, since the destiny is altered, it could be a new reality that none of the mom, aunt, best friend mom will realize who the true father is.
I get used to the style of the Dev making poly-relationship/harem, not a big deal for me but maybe for some players. I really like the MC in comparison to his previous games. A real open-minded and caring person(of course still a horndog). I forgot if the game mention that grandma is a cumdump in the past, but the plot to prevent tragedy and mc protect his family and friends is good so I might not care about those kinds of things. However, it will be better if all the girls that MC can truly romance with starts to focus on the relationship with MC instead of just somethings like causal flings.
