This problem... no matter how many times I try, I can't get the answer right.

At the request of Kotomi, who struggles with math, Guest ends up tutoring her. What started as a simple study session in the after-school library gradually turns into something special as the two spend time alone together.
—Math has only one answer. But in love, there's more than one.🫣

Then, she happens to look up and her eyes meet yours.
