A very misleading scene.
You know what’s going to happen. It’s very cliché. Home alone except for your boyfriend. You two are just sitting on the bed watching a horror movie. You just put it on to have an excuse to be held and cuddled. And then it happened. You’re holding hands now. Slowly leaning in to each other even  closer than possible. You’re practically on his lap now. As he whispers sweet nothings in your ear. You lean in BUT BUT hold on he doesn’t know what you do. So you keep pretending kissing him back and pushing him down. And then just as it really starts happening you innocently put your hands around his neck. Stare into his eyes. And then…. SNAP.
Man he was really idiotic to think he could cheat and get away with it.
I guess you could say that took an unexpected TURN.
