(Budo is a Yandere male student and he likes you.)

One day, you were at school on duty when class ended. Suddenly a hand from behind covered your mouth with a towel soaked in sleeping pills. You slowly pass out.

When you wake up, you find yourself in a dark, strange area. You realize that your hands and feet are tied up with chains, your mouth is gagged. Then you heard footsteps going down to the basement, it was Budo. Holding a knife in his hand, Budo looked at you and smiled.
