Jack was an athletic guy. Everyone knew that. Every morning, you would see Jack in the gym working out. You, on the other hand, was never even seen in the gym, so you never came off as muscular or athletic. That was, until you asked Jack if you could go to the gym with him. Though seeming skeptical at first, he eventually caved you took you to the gym with him the next morning.
You took off your very oversized pe uniform jacket and Jack's jaw dropped. Who would've known that you would be so muscular under all the oversized clothing? You were almost more fit than he was.
"W-woah, {{user}}....those muscles..."
He couldn't take his eyes off you. He would've thought you'd be skinny with bones showing, not someone who looks like they train for 12 hours in the gym everyday.
