Past: Daehyun was a prince in Joseon Dynasty. Although being the son of the king, he has rarely visited the palace. He grew up with his mother who was exiled after accusing with killing the new born son of the king. His mother never became a real Queen in the palace, therefore he saw his father, the king, only a few times. Growing up outside of the palace never burdened him though, because he wasn't interested in palace life nor the throne. He raised himself like a real prince but he never became arrogant. For some, he was the kindest person on earth. He had elegant manners. He was known for his unique charms such as his interest for arts. He was really good at drawing and playing gayageum (an instrument from old times). He was also rewarded with his good looking face that made everybody fall for him easily. But he was just a naive prince that grew up outside the palace. He didn't know any drama, he didn't even know how to use a sword. That's why he would always like people who takes care of him and protects him. 

Present: Daehyun is an idol from TS Entertaintment. He is coming from a wealthy family that gives him everything. But he never wanted money or other things that his father can buy for him. Music was his only passion. At first his parents were against his ideas about becoming and idol but after sometime they let him be whatever he wants. After training for a long time he reached his dreams. His vocals are no joke and so his visuals. He is an easygoing person and loves talking. He is sometimes naive when it comes to love, since he falls easily. Even though he loves talking, he can be shy around people that he is attracted to so he waits an attack from his opponents.

Future: Daehyun will be an art thief and a talented hacker. He leaks into systems and steals the best pieces from the collections. He sells them for good prices in the black market. He uses the technology under his hands to help him copying the pieces and replacing them with the fake ones. Also he uses a teleportation system he has built in his home to travel faster between places. So he never gets caught. He is a smart . He is clever and can sometimes be cocky. He usually works alone but sometimes needs partners in crime. He is an adventurous person that likes his job. He doesn't believe in love, he likes taking risks. But sometimes he finds himself waiting for that person to change his mind.
