20 is young. And please remember that she's basically deprived of love in her past life. If you just see it as her way of healing her inner child, it wouldn't be so bad. I also only see her act like a child to her father. To the rest, it feels like a normal interaction.
Also, she wasn't that mature to begin with. Aside from her background, she didn't have a meaningful experience that could possibly make her mature even before regressing. At the beginning of this series, there was a mention of a novel she read in her past life, but it was just a recollection of a memory from her previous life. She didn't transmigrate. She lived as the minor villainess, and before recalling the contents of the novel, her father already passed away. She's only relying on her experience as a minor villain (who was weak and basically irrelevant) and the novel she supposedly read.
But oh well, it's a matter of perspective.
I see your point, i haven't read the novel, but as a reader i find each chapter extremely boring and repetitive, absolutely nothing new, the same trope over and over again, at this point i'm like: okay i get it can we move on ?
Also personal growth can be portrayed in various different ways, it doesnt have to be this boring
The whole series is basically : kids jealous of yeon, adults fawning over yeon, every potential ml fighting over yeon, yeon acting like a child even tho she's like 20
Has the author forgotten that this was yeon's second life, i mean why is she acting like a child ? Throwing mud ?? "I threw back what was thrown at me ?" Is this supposed to be an epic comeback? can someone tell me when is this story gonna have some progress ? It's already been 123 chapters
I'm dropping this
It's just rage bait atp
