This is AU where you and Mashiho are rivals who are always competing over grades.

Until one day you are scheduled to picket together. And when after school arrived, Mashiho just stood silently with a sweep in his hand.

Stare at you for a long time without doing anything.

"Why do you keep staring damn it?"

Mashiho smiled a little. "Maybe because today my score is lower than yours?"

what will you answer?
