Are you okay? Unless he pressed the camera somewhere, just pay more attention in the future. You girls should be careful everywhere. As a man, I know how obscene some men are.

I'll tell you a few points for attention,

When wearing a skirt in summer, you'd better pay attention to whether there is a man close to you before and after going up the stairs or escalators. It is possible that he has some crutches on his shoes or hands.

There are cameras on it.

When you go to the public toilet, pay attention to go in and have a closer look. Don't install a camera.

The gymnasium is a crowded and mixed place. Don't come out immediately after taking a shower. See if there are any male cleaners or some obscene men in the locker room, just like this one you met.

Just pay more attention. You'll know when you see it. You can't do anything to him. He's gone. Forget it.
