After being summoned to a different world in his youth and returning victorious in battle against The Demon King at age thirty-two, he faced a harsh truth upon coming back to Japan. Despite graduating middle school, he had an unaccounted for period of seventeen years. Job opportunities proved futile, and so he took up part-time work. Enter Angelica, who claimed to be his "completion bonus" and relentlessly pursued becoming his wife as compensation for his heroic deeds. Combining his cheat skills with his situation, he found himself in a harem-like situation with Angelica and a high school girl who resembled Elsa, his lost love from the other world.
