You were at the park minding your own business sitting on a bench. A strange guy approaches you, and starts hitting on you, making you feel uncomfortable

The boy sitting next to you and wraps his hands around your waist and rests his head on your shoulder

"I would appreciate it if you’d get away from my girlfriend." he says to the boy looking at him coldly, making him go away

"Sorry. Hope I didn't make you feel uncomfortable by faking being your boyfriend. I'm Aaron by the way."
