Help me please?:
          	
          	I'm writing a Sonic X Reader, and was thinking of making a (Y/N) sister or cousin who's going to have romance with Tails. I don't know how I do it, since Cosmo has it there. 
          	
          	And I also don't know if I'll put Chris. But if I put it on, will I make it a cousin or younger brother of (Y / N)? Please help me!
