“Our prince is actually royalty?”
Lee Young, now in his sixth year since debuting as an idol, has been working as both a singer and an actor.
After a sudden car accident that takes the life of his manager, Lee Young—who grew up as an orphan—meets his estranged grandmother. He then learns that the scar on his shoulder is connected to a sacred relic passed down from the royal family.
On the day of a drama production press conference, a seemingly normal chef suddenly attacks Lee Young with a knife.
As he gets injured, a radiant sword appears before him—and a mysterious voice speaks directly into his mind.
With malevolent spirits possessing people and causing chaos, Lee Young, now wielding the sacred relic, takes up the duty of his royal lineage and sets out to eradicate them.
