In the grand, opulent halls of the Hwang family's palace, Hyunjin is a wild, free-spirited prince. Although he is the eldest son, he has always shied away from the responsibilities of the throne. His life has been filled with spontaneous adventures, extravagant balls, and the occasional public scandal-anything but the tedious world of politics and leadership. His younger brother, Jeongin, on the other hand, has always been the responsible one. He's intelligent, mature for his age, and far more suited for ruling, but there's one problem-he's too young to take the throne.
As their father's health deteriorates, it becomes clear that one of the two Hwang brothers will have to take up the mantle of leadership. Hyunjin is the natural heir, but he wants no part in it. He can't bear the thought of a life constrained by royal duties, ceremonial events, and endless political maneuvering.
Desperate to avoid assuming the throne, Hyunjin hatches a plan: if Jeongin could marry into another royal family or noble house, his youth wouldn't matter, and he could take over as ruler without the complications of succession. With that goal in mind, Hyunjin invites Prince Minho from a neighboring kingdom, under the guise of a trade agreement, hoping to set sparks flying between Minho and Jeongin. A marriage proposal between Jeongin and Minho could solve everything, and Hyunjin would be free to continue his carefree life.
