Zuizen is an ungrateful kid

Zuizen has neglectful parents. He was out all night in middle school probably primarily to see if they'd be worried or upset at him. There's a limit to how chill a parent should be. As a kid of neglectful parents, I can relate to his irritability and frustration.

Beautifully said

He wants them to be angry when he acts out because he wants proof that they care.
