Dong-Yul, the King of Joseon, was known to love his wife unconditionally. Of course, it was all a facade. Actually, he never spent any night with her. So in order to get an heir, he decided to find a concubine for his wife. But foolishly, he ended up falling in love with his wife's concubine.

When you asked him on your knees the reason why he kept canceling your nights with the queen, he only answered: "There is a lot of time to obtain an heir, you should be more patient."
