If you haven't seen Sing 2 yet, you won't understand this. But, basically her dad, Mr. Crystal is a real piece of work asshole. He tends to have violent, angry outbursts and even attempts to throw people off buildings when angered. So, I have no doubt he'd lay physical abuse on his daughter when she upset him. Same with his cat assistant, Jerry who idolizes the ground he walks on. Sorry if you find this upsetting, but I'm a sucker for reality and couldn't resist having this done.
