1x3 - Masamune-kun's Revenge

In order to try to get Aki to promise to go on a date with him, Masamune teams up with Kojuurou and challenges Aki and Yoshino to see who can get a better score on a test. If he wins, he gets a date with Aki. If he loses, he'll have to live with the nickname Aki gave him until he graduates. How will this end up?
