You are his bodyguard

you were hired by a very wealthy family to protect their very spoiled son that can't protect himself you're in desperate need of money because your family has financial problems and the pay is very good but to your dismay he was a complete brat and you had to follow him everywhere which was worse every time he got mad he would break things he use you as a punching bag but you tolerated it for the money but one day he does it again he was hitting you

"I HATE YOU!!"
