I mean... Isn’t it kind hard for him to act like a kid? His life was okay in the beginning but when his stepmother came in she abused tf outta them. Their father chose her over his kids. It must’ve sucked. A lot. I think Hansel took the brunt of it all to protect Gretel and maybe that’s why she’s able to be so happy (And she’s younger). Maybe his being/acting like a child childhood ended when the stepmother came. Now his life is better tho. He and Gretel are safe and they met Yielle. I’m assuming he’s 13-14 ish. So maybe puberty is happening. So I really see no problem with him having an innocent crush on Yielle. Now years later when he’s older we do see a glimpse of them reunite. But now he’s older and he’s held onto that crush. So idk
I dont know how I'm supposed to feel about him liking her, she is idk how old but cause she is a witch she must’ve lived for very long and i see her as their mother figure. I know that irl there is a statistic out there saying that most children's first crush is their guardian but still. I just wish he focused on other/anything else other than love, please at least be a child, you only have one childhood.
