Plus, i hate the mother... She sounds like those narcissistic, selfish, egoistical, and self centered person that only knows how to blame others but not looking at themselves and only want to be seen as helpless person that thinks what they did is right and that's the only think they can do. Without caring about the other person's feeling or the effect it can cause. If she's in the modern world, her place is at the welfare home.

I'm very confused of the idea of how time works with love life whether it's reincarnation, rebirth or transmigration from adult to a child and add romance inside and how reader sees it.
Rational side of me is [imagine an adult or young adult (18 >>) died and became a child and suddenly falling in love with a. A child their age (which is wrong due to their mental age.) or b. An adult (which wayy to old for their physical age BUT appropriate for their mental age.) Both sounds wrong in so many ways and any choices will get criticism because reader sees mc as a child physically (most forgets that they're previously an adult both man or woman).]
Logical side of me is [is it bad if the mc just took them as interest but never approach futher due to the age inappropriate and waited until they're fully adult to take actions/sees if they still attracted to them? I feel like it's a double standards knowing some of the reincarnations story get likes and pass for romance even when they used to an adult with adult mindset and adult behaviour but rebirth/reincarnated/transmigrated into a child and fall in love with someone around their physical age knowing that their mental age is double the number.
