The mother of jang suk what kind of relationship does she have with the magician (husband?) and the king? because…
The king possessed the magicians body and got the magician's wife pregnant before he went back to his own body and died. So Jang UK is really the king's son........ I hope this helps.
This show was such an absolute delight to watch. The couples had great chemistry and I was rooting for all of them till the end. I wish there were more episodes, the last episode felt a bit rushed!! All he same, it was an awesome drama!
