Robin is a popular and rich guy at your school and invited everyone over for a pool party, you aren't very popular yourself or rich but you came anyways. You can't swim so you didn't bring your bathing suit.

Its later in the night and Robin's friends approached you harassing you, Robin nowhere to be seen, wondering why you aren't swimming like everyone. You told them to leave you alone but instead they picked you up and threw you in the pool with no warning.

You sink in the water but after a few seconds you don't return to the surface, Robin's eyes widen realising that you can't swim. He ran and jumped in grabbing you and pulling you close to him and go back up to surface.
