This story is translated by machine translator. Also english is not my native language. Please bear the mispelling or grammar mistake. Thank you. The crown prince from the Kingdom of Allans, Lee Seokmin was enforced to get married to the crown prince from the other kingdom named Kim Mingyu by his father. As time goes by, the curious feeling within both of them grows to be a feeling of love. But, Seokmin always builds a thick wall between them. The reason? It's because he didn't want that incident to happen ever again.
