By day, Jin Ho-Rang 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 Ah-Jo, he can hardly believe it. Back then, Ah-jo was a beautiful omega who seemed to shine like a flower. Ho-Rang is told that Ah-Jo’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, Ho-Rang goes to meet him again. Instead, he finds a towering, wildly different man who barely resembles the gentle Ah-Jo he once knew. Caught between nostalgia, shock, and an unexpected new dynamic, Ho-Rang is pulled into a whirlwind engagement that is nothing like what he imagined, turning his quiet life into a chaotic and heartfelt romantic comedy.
