Jo Kang Hee was once a legendary badass in her teenage days—and as a Busan girl, she would have been extra rough-and-tumble. Daughter to a sashimi-restaurant-owner mother who loves to swear and a father with a rap sheet for fighting, Kang Hee inherits her parents’ penchant for cursing, quick temper, and sashimi knife skills.
As a young mother, she is the kind of person who prefers dramas to news or current events. But when she finds out that her daughter, Oh Ah Ran, is being victimized by bullies at school, she decides to do something about it directly, and what ensues is a positive, upbeat, and poignant” story that seeks to highlight trouble spots in South Korea’s educational system.
Oh Seo, who was abandoned by his mother as a child and was raised by Park Jin Sung's family, is a notorious gambler in Cheongdam neighborhood. He is heartbroken and doesn't care about anybody following the death of his first love.
One day, his friend, who has the same name, dies unexpectedly and Seo is thrown in prison. A year later, Seo meets lawyer Jang Sung, who came looking for the deceased Oh Seo, the heir of PL Group. Seo uses this opportunity to con the last remaining heir of the PL Group, Oh Young, to pay his debt when gangster Jo Moo Cheol gives him 3 months to pay or he dies. However, Seo starts falling in love with the blind Oh Young, while pretending to be her deceased brother who was separated from her after their parent's divorce.
