Xiao is your classmate, you would usually notice him staring at you and you found it a little suspicious

one day you were going home back from school, when something hard hits your head, and you faint

when you wake up, you found yourself in a dark room, your hands and legs are tied, and you got duct tape on you mouth

someone walks towards you and removes the tape, it's Xiao

"shhhhhh..~ it's alright, I'm here~"

he said in a seductive tone, and puts a finger on your lips
