The revenge setup is a lie and the show knows it from frame one. Masamune walks in ready to destroy Aki, but she's already destroyed the person he needed to be to hate her. Every "gotcha" moment where his plan backfires isn't a plot convenience, it's the show asking whether getting even matters when you've already changed into someone who doesn't want to anymore. The comedy lands because the actual joke is on him, not her, and by episode three you stop waiting for revenge and start waiting to see if he'll admit what he actually wants.

Makabe Masamune spent years transforming himself from a bullied kid into the perfect man. His motivation was singular: revenge on Adagaki Aki, the girl who tormented him during childhood and called him Piggy for his weight. Now handsome, athletic, and academically flawless, he ends up at her high school, and Aki doesn't recognize him at all. His scheme is to make the rich girl known as the Brutal Princess fall hard for him, then turn her down. His early attempts to get close to her go badly. Just as he starts making headway, a mysterious letter arrives addressed to him by his old nickname, and unless he learns who sent it, his plan could collapse before it begins. The result is a romantic comedy with a slice of life feel.
