you were at your boyfriend's house reading a book in his room when he came into the room, a guilty expression on his face, he scratched the back of his head before saying

“I-I cheated on you..”

you looked at him expressionlessly and replied a simple “ok” before returning to your reading. He looked at you a little shocked

“you’re not angry?”

You looked at him and laughed softly. In rage, he took your book and threw it against a wall before shouting

“why are you laughing!?”

He raised his hand to hit you when he was blocked in his momentum by a tattooed hand. And a hoarse voice sounded behind him

"You woke me up asshole. What do you think you're doing by raising your hand on her."
