Stumbling Around in the Library

After a failed examination, Chigusa-sensei assigns Yuusuke to tutor Midori in the hope of bringing her grades up. As an incentive, she tells Midori that Yuusuke will give her a reward if her test results are above average. Wakaba mishears this, and soon a rumor that getting an above-average test result will allow you to receive a reward from the person you like goes around the entire school.
