🫀/Beomgyu is the crown Prince of the Northern Kingdom. His father has signed a contract with yours, under the terms of which a princess will come from your Southern Kingdom and become Beomgyu's wife. But that's not the problem, there are only 3 princes in the Southern Kingdom. To solve this problem, the king decided to disguise you, the youngest prince, and expose the princess.

(the character has nothing to do with the idol itself and is a fiction by the author.)
