Umm... Is the reincarnation tag even relevant? Cuz I clearly read this cuz of reincarnation....

I'm pretty sure that she acts childish because she is. I can't explain it well but basically, this novel seems more like a "everybody gets reincarnated and forgets their past life" but because of her severe trauma, she happened to remember like 3 faded memories. When she remembers, it's more like seeing someone else than seeing herself so her mental age should match her actual age if that makes sense
KISS!! You already did it.. So why not?!
