Lee Tae-rok, a great tye, who has no crown prince or king, welcomes his nephew Lee Nan-young in the year when he is thirteen years old. A child who has no talent and is too gentle in nature. At first, he took over his nephew, which no one expected, as a request from his brother, and Taerok thought it was just a responsibility at first. However, Nanyoung grew up looking at Taerok, and the desire to resemble her gradually changed to an inexplicable feeling. Taerok noticed the change and kept the line pretending not to know. But in the end, Nanyoung kissed another man to confirm her feelings, and Tae-rok had to see the scene— "My nach-law is my scandal. This uncle will also be my nephew's scandal."
