Masamune-kun's Revenge

Makabe Masamune was a chubby little kid but after years of training, he manages to lose weight and becomes a hot guy. This was all so he could get revenge on a girl who bullied him as a child by making her fall in love with him and dumping her in return.

Masamune recieves a letter with the words "Pig's Foot" written on it and realizes someone knows about his past. Masamune tries to find the person who sent the letter, and it ends up being someone rather surprising.

In order to get Aki to promise to go on a date with him, Masamune 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.

Masamune is planning his strategy to get revenge on Aki by reading a shojo manga, but Yoshino tells him he's doing it wrong. Rather than the aggressive approach he's been using, Masamune tries to get Aki to pay attention to him by ignoring her.

Masamune saves Aki as she's almost hit by a car. The mysterious, beautiful passenger comes out and says that she was waiting to see Masamune. A few days later, a new girl transfers into Masamune's class, and Aki's mood takes a turn for the worse.

Neko tries desperately to win Masamune's affection. However, Masamune seems rather oblivious to this fact and when he gets home, he finds Yoshino and Neko there, making him food.

After finishing their exams, summer vacation finally begins. Masamune plans his next move to get closer to Aki, and heads to Tsunade Island along with the others to spend time at Aki’s summer villa.

Masamune gets an unexpected call from Aki on his cellphone. Masamune then realizes that the picture of him and Aki when they were children is gone, and he’s certain that Neko is the one who took it.

After being rejected by Masamune, Neko disappears. Aki seems to feel sorry for Neko since she was rejected, and then Masamune asks her if she remembers the nickname “Pig’s Foot.” When they finally find Neko, she starts talking about the past...

Things get complicted for Masamune when Gasou Kanetsugu shows up.

Whoever gets more votes for their production of “Snow White” for the cultural fair, get to dance with Aki afterwards. The battle has begun between Masamune and Kanetsugu. Suddenly, something rather unexpected happens to the both of them...

Despite all the trouble, the cultural festival is now over. They all end up having a karaoke after party and battle it out there. What will become of Masamune’s revenge?!
