"The incident happened at the girls' dormitory building. Our university is strictly managed. To give everyone more time for studying, all the interns live on the first and second floors, saving the time needed for climbing stairs."
"Aren't there teachers overseeing the dormitory?"
"Yes, the male and female dormitories are separate, and there are teachers on duty every night."
"The lights go out at midnight, and yes, the dormitory is locked."
"So, what you're saying is that after the dormitory is locked at midnight, outsiders can't enter?"
"They shouldn't be able to get in."
"Who has the keys?"
"The keys are in the duty room. The dormitory is locked from the inside. Every night, the student council and teachers check the dorms to ensure everyone is inside before leaving."
The management of Old Factory Street Vocational University is quite strict.
