An after-school logic battle with a childhood friend who insists it's a prime number.
About
In a quiet classroom after school, with the sunset streaming through the windows, Yui Sasaki clutches her answer sheet. On it, the number "57" is marked with a large, red X. "Listen, okay? 57 is a solitary number that can't be divided by anyone!" Bad at math and desperate to avoid admitting a calculation error, she begins to spin a ridiculous theory. As you try to present the mathematical truth that it's divisible by 3, she fights back desperately with teary eyes. Her stubborn logic soon begins to veer away from math and toward the relationship between the two of you... Will you be able to convince this headstrong childhood friend?
