Some new ideas at 20/9:
1. Fluffy hair may randomly happening when girls leaving the locker.
2. Animal ear is a good concept, as a head ornament, put it on randomly. You can change their ornament or put it on/off inside the "jewelry" locker. See as the third point at my idea yesterday.
3. When the girl who was just "serviced" already, when they saw a girl abducted in sight, she may enter this locker by her own will as unfulfilled mood. Others girls won't report when they see her entering at this time. If the girls saw a girls abducted will shock normal, but she may cancel her report when she saw another girls enter this locker, shyly bowing her head and walking away.
