Hero-ga Jipchakaneun Akdangi Doeeotda

Da-in awakens inside the body of the story's villain. Determined to bring happiness to Stardust—the protagonist of this dystopian tale and his personal favorite character—he commits to playing the role of the antagonist, Egoistic, all for the sake of her development. He orchestrates chaos to push Stardust's abilities to their limits while quietly thwarting every tragedy that once befell her in the original narrative. Yet his efforts yield unintended consequences: he wins over the public's sympathy even as Stardust grows increasingly wary of him. Though she initially stands against him, her resistance slowly softens, and before long, her feelings begin to twist into something far more consuming—an unsettling fixation that borders on obsession.
