HE WAS ABSENT ALL THIS TIME!!? Ik it's Yui's real DAD but how can he just easily ask for a custody of his child? When he's not even there to take care of her? And yui already had her attachment with her caretakers. He can just probably do a co-parenting shit like any other divorced parents do...
Hangyeol could've got a bigger knife and carve that tattooed body with his own blood
