After losing himself in a dating sim marathon, Fudou Niito, a self-professed lazy NEET, is jolted awake to a bizarre reality—he's trapped inside the very game he obsessed over! But here's the twist: he's not Verner, the protagonist, or Eterna, his beloved waifu. Instead, he embodies Ellize, the despicable imposter saint who tormented Eterna. Determined to rewrite the game's narrative, Niito's mission is clear: orchestrate a new fate where the suffering heroine, Eterna, finds her long-overdue happiness. To achieve this, he must become a master matchmaker for Verner and Eterna while elevating the fake saint's status. Will this unexpected role reversal lead to a joyous resolution for his cherished character, or will the imposter's meddling backfire?
