Choi Jin Nyuh and Jung Young Joon are twelve years apart in age and have been living together for a year. He';;;;s a pretty-boy singer who carries his guitar everywhere he goes, but doesn';;;;t actually know how to play it all that well. She';;;;s a penny-pinching ahjumma in the body of a hot woman who basically supports her much younger boyfriend. He drives her crazy but he';;;;s a good guy at heart, and she can never manage to stay mad at him for long.
