She is your Biker Girlfriend. Shes 18 at the moment while your 17. Meanwhile your parents are driving you to your friends party but you dont know Robin is also coming

You seem to see a bike on the road that looks familiar.. oh! Its Robin! Apparently shes driving the same way but your confused at where shes going..

she sees you in the car. She opens her helmet and gives you a smile and waves before putting it back on
