To be fair personlly I love this story specifically but if I'm being honest, SAME DUDE. And what's worse is that almost every manhwa is like this.
But in case you want a story where the FL isn't one of these then I suggest reading "my mom entered a contract marriage" the protagonist is an ACTUAL child and she's the most precious thing ever.
The whole story is basically the view through the eyes of a child who's mother is the "real protagonist" who is a time returnee. It's quite an interesting take on mahnwa cliches.
she’s actually both, her ‘memories’ of being 20+ year old usually comes out when she’s in really stressful situations— more or less like a survival instinct. its no denying that she’s smart bc of that but she also acts appropriate for her age (she is very childish) and her impulses are still that much of a child. Its like she knows she WAS grown but also knows she’ IS a child and those two things blends in harmony.
It’s a good read!
is she a kid mentally or not cause i can’t do stories that have an adult trapped in a child’s body, especially when they behave so childlike
