Geez I sound old by saying this, but Ive met many 20 year olds act like children... the older you get, you notice how immature/naive many of them are... well tbh, Ive seen many immature ppl no matter the age...
You're right
I'm reading the novel and yes, MC acts like a child. Though he says he's 20 but it seems that an actual bird has transformed into human not that he was originally a 20 year old boy
