Gu Yi'an had been in a men's restroom before, so she knew that the structure of a men's restroom was different from that of a women's restroom!
Outside were a few urinals for men to stand and pee.
Inside were individual stalls.
Fortunately, there was no one inside at the moment. Gu Yi'an breathed a sigh of relief, but her face still couldn't help but turn red.
After all, she was a normal person. Rushing into a men's restroom intentionally still posed quite a psychological barrier.
Before she went in from outside, Gu Yi'an noticed something: after the restroom, right next to it was the monitoring room.
But after Bo Yi went into this restroom, it was impossible that he would drill through the wall to go to the monitoring room next door.
So, the problem was still in this restroom.
Gu Yi'an looked up and down but didn't find any secret doors in this restroom.
The urinals had no issues, the walls had no issues, so it could only be the ceiling...
Gu Yi'an looked up.
