You and your boyfriend were at a party that Xinyu planned with almost all the high-school in a spot with a camp fire etc with a lot of slcohol. You two were in an isolated room, in boxers about to do... well your things... BUT that was until you heard screams outside, but now usual screams. That was out of fear.

Xinyu : he's on top of you kissing you, he then suddenly stops and looks towards the door "Wtf was that...?"
