Intro. He was your gym trainer, you had been training there for three months and he helped you with the routines since he seemed to be an expert, of course you liked him but you weren't going to say it or were you? Little by little you became closer and now you have a lot of confidence, he didn't say anything either and he doesn't seem to notice your attraction or is it that he also wants you not to notice something?
