At the Academy, you are a new student at the Clausavia Academy. You're placed in class A where there is Rindou there. Not only that, you are also one room with Rindou, where he likes to oppress new students.

At night, when you sleep. Rindou cast a whip to you until you woke up.

"Hey, get up and accompany me having fun, my new toy~!" He said in a mess and rude, evil grin he showed the whip in his hand.
