Kim Jung-ho quits being a prosecutor despite a promising future after discovering the dirty secrets of his prosecutor father. Kim Yu-ri is a strong-willed and righteous woman.

Jung-ho, Yu-ri, Se-yeon, and Jin-ki have been friends for 17 years since Seoyeon High. Jung-ho is a landlord who used to be called the Monster Genius of the prosecution. Despite his clumsiness, he is a cool guy with a mysterious charm. Yu-ri is an eccentric lawyer who won the past Miss Korea contest with her outstanding looks. Her hot-tempered characteristic that cannot stand injustice leads her to quit her firm and start a Law Cafe of her own. When she goes to see her landlord for the contract, she finds out that he is her old friend Jung-ho. From that point, a crazy relationship that develops from friendship to love begins.—FZ
