A few years ago, our good man Makoto was pranked and humiliated by a group of schoolgirls, which caused him to get fired.
By some twist in destiny, at his new job, he bumps into that schoolgirl once again (Nene Yoshitaka), as she is now a co-worker.
To piss him off even further, Nene is set to get married to the president’s son.
In that junction, he finds a way to get his revenge via brainwashing.
