Dangerously Close to

I only know that my grandfather adored my grandmother, to the point of being "crazy" about her.,If you don't respect me, it's fine. But if you disrespect your grandmother, I'll cook you some chestnuts and pork belly.,At that time, I already found it unbelievable. I ran to my dad's bedroom and blurted out, "Is grandpa a pervert I saw him holding grandma's feet. Does grandpa have a foot fetish"。
