Masamune-kun's Revenge

A scorned kid returns as a heartthrob, plotting love‑revenge that spirals into chaotic romance.

Masamune Makabe spent his childhood as the target of Aki Adagaki’s cruel jokes, earning the humiliating moniker “Piggy” for his plump figure. Determined to shed that scarred identity, he threw himself into relentless training, emerging as a strikingly handsome but self‑absorbed teen. Now enrolled at the same elite academy as Aki, Masamune hatches a meticulous scheme: make the icy “Princess” fall head‑over‑heels for him, then crush her heart just as she once shattered his. He dives into the school’s social whirl, courting Aki with a blend of charm and calculated indifference, only to stumble over his own arrogance and the tangled web of his classmates’ affections. Just as his revenge plot begins to gain traction, a cryptic note arrives, signed with his old nickname. The reminder of his past humiliation forces Masamune to confront the lingering wounds he thought he’d buried. With his confidence shaken and his motives questioned, he must untangle the mystery of the letter’s author while navigating a harem of eager peers, each pulling him in a different direction. The series balances slapstick comedy with the bittersweet sting of teenage insecurity, delivering a roller‑coaster of scheming, misunderstandings, and unexpected heart‑warming moments.

A romantic comedy where a formerly overweight boy transforms his body to enact an elaborate revenge-rejection scheme against his childhood crush, surrounded by a harem of romantic rivals. Expect moderate fanservice and a premise built on emotional manipulation that the show gradually complicates but doesn't fully condemn.
