Meet Gero, a legendary specialist from an elite clan of hitmen that has stayed in the shadows for centuries. He is a master of his craft, but outside the world of assassination, he is a complete disaster. Having spent his entire life in the dark side of the business, Gero has zero social skills and even less experience with women. To him, marriage is a distant dream that simply does not belong in his violent reality.

However, everything changes when his clan issues a chilling ultimatum: produce an heir to carry on the lineage, or they will force his innocent younger sister into a life of brutal training. With his sister's future on the line, Gero is pushed to his absolute limit. Desperate and out of options, he turns to his most unlikely ally—a brilliant marriage swindler he was originally sent to eliminate. Together, they embark on a chaotic, high-stakes quest to find Gero a wife through the most grueling battle for marriage the world has ever seen.

What follows is an explosive mix of top-tier action and heartwarming comedy as Gero navigates the terrifying world of dating while fending off rival killers.
