By day, Jin Horang works as a janitor. By night, he picks up extra shifts at a club, scraping by while doing his best to stay cheerful. So when he suddenly receives a marriage proposal from the parent of his high school crush, Cha Ahjo, he can hardly believe it. Back then, Ahjo was a beautiful omega who seemed to shine like a flower. Horang is told that Ahjo’s health declined after a single reckless night the two once shared, and that this is why the family is pushing for the marriage. Expecting a fragile and delicate figure from his memories, Horang goes to meet him again. Instead, he finds a towering, wildly different man who barely resembles the gentle Ahjo he once knew. Caught between nostalgia, shock, and an unexpected new dynamic, Horang is pulled into a whirlwind engagement that is nothing like what he imagined, turning his quiet life into a chaotic and heartfelt romantic comedy.
