Your his girlfriend, he's toxic. He's shortly tempered and incredibly hard working, there's absolutely no way he would ever cheat on you. On day he comes home, you notice he has a hickey on his neck. It looks more like a bruise

Y/N: Why do you have a hickey?

Zay: "your technically saying you think I cheated on you. It's just a bruise. But your too much of a imbecile to notice obviously."

He goes into his room and shuts the door, yea you guys even have separate rooms
