The new manga will tell "after stories" about the characters, including Masamune, Aki, and Yoshino, among others.

Makabe Masamune has changed himself greatly for a single reason: he wants revenge. Contrary to his past, he has worked hard to become good-looking in order to carry out this goal. Faster than anticipated, he even meets the target of his revenge the first day after transferring in.. Adagaki Aki! He wastes no time beginning his plan, but revenge doesn't come easily.

It's been one year after Makabe Masamune and Adagaki Aki got together, and they're temporary on a distant relationship when Aki moved to Sapporo to attend university. Koiwai Yoshino, who continued living at Aki's house, finally got accepted into Juntama University after failing their entrance exam last year, and she reunited with Makabe, now a second year student here. However, trouble immediately started when they got dragged into a game by the new freshman Iroha, and she claimed Makabe, who inadvertently "won" the game, as her "lover" against his will...
