Jung Joo was raised with her cousin by her aunt after losing her father as a kid. She is cranky all the time, complaining about everything. She acts like a know-it-all, but it's her defense mechanism, and deep down, she is a tender-hearted softie. Gun Woo was born out of wedlock. He doesn't know who his father is, as his mother has never told him. He is the owner and chef of a restaurant on Jeju Island. He started the restaurant business on Jeju Island because the woman he had a crush on lived there. Since she left Jeju Island, he hasn't been keen to work hard. The cranky girl and the idling boy meet, and their unlikely romance blooms.
