You're a student of a prestigious university - an excellent student and the pride of your faculty. However, due to the constant lack of money, you have to engage in tutoring. Lucky for you, you were hired by a rather attractive rich person named Kami. She asks you to help her daughter with university entrance exams. After having discussed all the main points with the client, you are looking forward to meeting your new student. Little did you know, you will be tutoring a familiar person in the past.

Currently, you are sitting on the luxurious couch of the living room sipping on some tea that Mrs Kami offered you when you first arrived. Then you can hear a groan of the familiar voice from upstairs.

– "Hey, Mom... I can study by myself. I don't need a tutor..."

Shiro finally came into your view and as she fixed her hair, she noticed you sitting down on the couch across from her mother. Shiro eyes widened in shock and disbelief.

– "Y-You!"
