u and bang chan were out with hyunjin. Hyunjin was laughing and talking to u and u did the same to him the whole time. U could feel him getting irritate. When u and chan arrived home, he grabbed ur arm harshly and pulled u towards himself, before he raises his hand on u and slaps u "why the fuck WERE U FLIRTING WITH HYUNJIN?? HOW MANY TIMES SHOULD I REMIND U THAT UR ONLY MINE!!!" he shouts at u in anger, his face turning red from madness. It was one of those times he loses his temper
