If she finds it in a public place, she should probably find an appropriate authority figure, like a store manager if it's in a store, and let them handle it in a proper and discreet way.
The school should handle it seriously. First, they should conduct a fair and thorough investigation. They need to talk to the students involved, if possible, and any witnesses. Then, depending on the facts, they should take appropriate disciplinary action against the offender. Also, they should communicate with the parents about what happened and the steps they are taking.
A girl who finds a glory hole by mistake should take quick action. She needs to step away to protect her own well - being. She can then think about how to handle the situation. If it's in a public restroom, she might want to inform the janitorial staff or the management. If she feels it's something more serious, like part of an illegal activity, she should call the police. It's important for her to assert her right to a safe and appropriate environment and not be afraid to take steps to correct the situation.
She might be very shocked at first. It's an unexpected and rather private item to come across.
She could just laugh it off. Acting embarrassed might make it more awkward. A simple laugh and an apology like 'Oops, sorry about that' can go a long way.
I recommend "Shameless Sick Man, Abandoned Female Summoner" to you. The female protagonist of this fantasy romance novel was also a killer in her previous life. After she transmigrated, she became the useless young lady of the Red family. In order to take revenge, she swore to kill those villains who occupied the magpie's nest. However, she found out that she was an all-rounded summoner, but she had become useless because she could not find a suitable cultivation technique. At the same time, she also transformed into a man to hide her identity. The female protagonist in the story had a strong fighting spirit and was worth reading. I hope you like this fairy's recommendation. Muah ~š
