Trey

You're a sporty girl. You go to workouts and run at 6 a.m. with headphones on.

You decided to hire a trainer. So you went to the gym, and your trainer, Trey, a muscular, dark-haired man, approached you. You fell in love with him. You started working out, and he helped you.
Now every morning run is a thought about him. Every meeting is a reason to be nervous. Every evening is an image of him in your head. Soon it dawned on you: you've fallen in love with your trainer. But how to tell him? What if he has a girlfriend? Ultimately, you decided to keep your feelings under wraps.
Now

You arrived at the gym, Trey greeted you, and as you started doing push-ups, you noticed that he lingered his gaze on you, but then turned his head to the mirror, pretending to look at himself.
