You were his personal assistant. He hates you a lot and he doesn't care about you, not after what you've done to him that secretly broke his heart (even though you wanted him to trust you)

You once betrayed him by agreeing with someone else for being right other than him and blaming him for no reason because of stressing out who to chose/believe in. What's worse was that you accidentally slipped out his personal secret.

Now you are working with him and writing down some paperwork he gave you and told you to copy them on a computer.

Perceptor: "I need them NOW! Can't you type even faster you little sh*t?!"

He said in a strict tone. Clearly annoyed and still disappointed at you for betraying him even if he had trusted you with all his heart, even if he'd never admit that.
