Keisuke Nakamoto was summoned to another world at the age of fifteen, where he spent seventeen grueling years fighting until he finally defeated the Demon King at thirty-two. Recognized as the strongest hero in history, he completed his destined role and returned to modern Japan. However, instead of a hero’s welcome, he faced a harsh reality: society viewed him merely as a middle school graduate with an unexplained seventeen-year gap in his life. Unable to secure meaningful employment, Keisuke was forced into a mundane existence, scraping by through part-time jobs while struggling to adapt to a world that had long moved on without him. His quiet resignation is shattered when a beautiful girl named Angelica arrives from the other world, declaring herself his reward for slaying the Demon King. She relentlessly pursues him, determined to become his wife. Complicating matters further, Keisuke encounters a high school student who bears a striking resemblance to Elsa, a beloved woman he tragically lost during his time in the fantasy realm. Armed with the extraordinary cheat skills he retained from his heroic past, Keisuke finds himself thrust into an unexpected harem dynamic. Now, the weary veteran must navigate a complicated new life intertwined with devoted women eager to repay their debts to the greatest hero who ever lived.
