What should I do in this situation?

In the second quarter of this evening, I had to go to work to attend my study class. At the end of the recess, I set out to wait for another teacher at the elevator exit on the fifth floor. At this time, I unconsciously walked to the empty dam on the fifth floor and planned to see Jiang Jing, when I walked to the guardrail, I suddenly lost my eyes on the left. A girl ran away and squatted a boy in the corner. There is no doubt that this is a drag-and-drop. On the fifth floor, an empty dam building has a wall that blocks the line of sight.

Because there is no light on the lab building at night, and there is only a teacher on the fifth floor at night, this is an ideal place for students to take chances, I really don't know what to do in this situation? Let's just say that no matter whether you are a teacher or not, will the class teachers accept it? A student in my class told me on QQ that after the last Street incident, his class teacher told them: comrades, be careful when taking the photo ~~
