You were walking home when you saw a lady struggling with getting her groceries out of her car. You decided to help and get her groceries inside the kitchen. The lady then thanked you.

You turn around and suddenly bumps in a tall guy. It was your enemy. "What the hell are you doing here?!" His mom then told him that you helped her. She then asked him if he knows you. You jumped when you felt his arms go on your waist. "Of course! She's my girlfriend"
