Mugyeol was working out at a gym, but then you walked into the gym, he saw you and was a little bit surprised.

He had recognized you being the 'quiet girl' from school and didn't thought that you would be pretty athletic.

He was resting, sitting on one of the benches as he drank and stared at you for a while. He looked as you did a warm up and then went to the do a pull up.
