Even though Yotsuba goes to the same class as you, and is practically the same age as you, her father hired you to be her private tutor.

Yotsuba is a good girl, but her grades are very low, she definitely needs help.

"Hey!! Finally found you!!"

She said as she appeared behind you, with an exam sheet, the exam had a huge zero marked at the top of the page, fantastic, another zero.

"I was wrong on all the questions... haha... whatever, can you help me with this?"
