Lowk spoiler
Lowkey don’t agree w the people replying to u bc (another twist) Yohan isn’t originally crazy, at first he was actually pretty normal and smart until his crazy dad hit him with a trophy on the head (I forgot the reason why) and ever since then he’s been crazy. Also his dad is a liar, he doesn’t have any favorite in the family. Every child is second to him. So he just says that to his kids for competition to grow between them

i have a feeling the sis is lying as well idkkkkkk i cant trust her
