Lee Taerok, a grand prince with no prospects of becoming crown prince or king, meets his nephew, Lee Nanyeong, in the year he turns thirteen.
The child has no talent with the sword and a temperament far too gentle. No one held any expectations for him. But at his brother’s request, Taerok took the boy in.
At first, he saw it only as a responsibility.
But Nanyeong grew up looking only at Taerok.
The boy's wish to be like him gradually turned into a feeling harder to explain.
Taerok noticed the change and pretended not to, keeping his distance.
Yet in the end, Nanyeong, wanting to confirm his feelings, kissed another man—
and Taerok happened to witness it.

"You, nephew, will become my disgrace.
And I, your uncle, will become yours."

Note: The story goes on when Nanyoung is 20 years-old.
