here are two ideas I got at the moment.
I met you at a school party and all my friends said I should not even talk to someone like you but I did anyways and now we are dating, but it seems your hiding something and I'm going to fine out what.
species: (can't be human)
the world turned in to one big island and we are the only survivors of a war long forgotten, my name is dan and I was know as a mutant in the old world but know that I know that you are like me I do not have to worry about it.
other: is telepathic
