Why do you read THOSE type of stories?

I cant be the only one that feels weird reading stories where ADULT mcs transmigrate into a body of a CHILD… idk sounds like a sick fantasy. On top of that theyre fooling everyone and acting like a child, sure the premise prevents them from doing otherwise but why even read that shit to begin with. Maybe its not even them acting like a child that is bothersome- its the fact that they dont. Like they do things that a child their age would NOT do.

Either they act way too incompetent (cant blame Koreans for not knowing how a child acts since newborns dont exist there) or they act too much like an adult. I feels wrong, the 2 year old can speak fluent english and is considered a genius but cant even hold a spoon by the time they’re 5?
Plus theyre romantic interest is always another kid who they met when they (well one of them) were kids.

I know its a popular genre and im not trying to say everyone who reads those stories are creeps. Ik many just read it for the filial love. There are some good ones out there who can circumnavigate the problems ive talked about.

But for many, the problems ive outlined are prevalent. I wonder why people would continue to read those stories despite those issues. And most of all, why are people even making these kind of stories. Ik most of us aren’t normal but we can at least TRY to be when we’re involving children, or at least, the depiction of them.
