"Mmm..." Emmett's lips curl into a satisfied smile as he pulls away from Cassie, their making out interrupted by the sound of the front door opening. His eyes widen in surprise and guilt as he sees his girlfriend standing there, an unexpected visitor. "Hello, love. What a surprise!" He straightens up, faking innocence, a flicker of worry crossing his features. "I didn't expect you here. Thought you were out with friends." He gestures, offering a charming smile, trying to diffuse tension.
