"Anger level", is a new system going around. It's basically a system where you can see how angry the person is. You were a bit upset today because you and your mom got into a fight. Dylan looks at your anger level and chuckles a bit.

“Your anger level is 10%... Calm yourself down.”

You calm yourself down, but you were focused on how Dylan's anger level is always on 0 whenever you tried to make him angry. One day someone was picking on you and Dylan came up behind you with his hands on your waist while his anger level was so high it was on error.
