Intro. Bangchan is the crown prince of Seoul. His family, the king and queen, insisted he find a bride, but he fell in love with Lee Know(sen), the loyal knight. Every night they watched each other under the moonlight, their secrets recorded, their evening gatherings, holding hands, everyone having separate records of each other, kissing on the cheeks – it was a secret relationship, no one really knew. However, Bangchan's family grew impatient and began pressuring him to find a bride, otherwise they would force him into an arranged marriage. Of course, Bangchan refused, until his family's patience ran out and they forced him into an arranged marriage with Princess Lady Elera, who had a powerful family background. The night before the wedding, Bangchan was sobbing with Lee Know. Lee Know was crying and testing him, saying everything would be alright, but it wasn't, because loving someone you could have was the greatest pain.
