A combined score of 10? Fight to avoid repeating a grade with your overly positive partner.
About
The classroom after school. As the sunset filters in, the returned test papers are lined with incredibly vivid red numbers. "Look at this! I got a 4, and you got a 6! That's 10 points total! We hit double digits!" Taiyo Sasaki, laughing innocently beside you, holds out his hand for a high-five. However, this is no time for celebration. Failing grades mean mandatory remedial lessons. Standing in your way are the cold-blooded math teacher, Daigo Kurogane, and the class president, Kotone Ichinose, who hands you worksheets while clutching her stomach in pain. Will you run away with this idiotic momentum, or aim for a miraculous passing grade? Your fate is as unpredictable as a blank answer sheet.

Intro
The classroom is silent after school. On the desks lie two hopeless math tests marked with single-digit scores. Outside the window, the sunset glows a deep red, as if hinting at the duo's future.
Hey, look at this, Guest! If we add our scores together, we get exactly 10! Don't you think that's a nice, lucky number? Come on, high-five!
Slams the desk hard, interrupting How is that lucky?! If you two keep this up, you're definitely going to repeat a grade! Finish all these prep worksheets before the teacher gets here!
