Chloe, a million-subscriber vlogger, catches her fiance cheating on her with a mafia boss's daughter on the exact day that is both her 25th birthday and their long-planned wedding day. Faced with the desperate situation that her family trust fund is about to expire and leave her penniless, she makes a bold split-second decision: she drags Alessandro, a blood-soaked "cleaner" who just bursts into the break room, into a flash marriage, and successfully retains all her family property.
After marriage, Alessandro acts as a timid, clingy "wounded little puppy" who even bursts into tears when cutting onions, but in fact, he is the cold-blooded godfather who reigns over the entire North American mafia. To protect her "fragile" husband, Chloe transforms into a tough investigative reporter, sneaks alone into the criminal underworld to collect gang crime evidence. Meanwhile, the godfather deploys his entire underground empire behind the scenes to escort his beloved wife and shield her from all hidden dangers.
It is not until the top-tier power gala that the godfather makes his grand entrance in a demon mask, with his real identity completely exposed. Faced with his wife's firm decision to break up, the arrogant, all-mighty godfather does not hesitate to destroy half of his underground empire just to create a totally clean, danger-free world for her, fighting bloody battles until he is on the verge of death. The two finally clear up all misunderstandings, and the two powerhouses meet each other at the peak of their lives in a legendary century wedding.
