15 parts Ongoing Crown Prince Kim Mingyu was ready to marry the perfect princess - gentle, obedient, and a flawless political match.
But days before the wedding, Princess Jeon Eunah vanishes without a trace, leaving behind only a scandal and a kingdom's panic.
The solution? Replace her with her older brother, Prince Jeon Wonwoo.
At first glance, Wonwoo is everything Mingyu expected - soft-spoken, delicate, and far too pretty for his own good. Mingyu assumes he'll be easy to control... maybe even a little useful for running errands and keeping out of the way.
But the "sweet" prince isn't sweet at all. Underneath that angelic smile is a sharp-tongued, unapologetically bratty royal who flips the script - making Mingyu fetch tea, polish crowns, and carry his load.
Now the soon-to-be King of Solhaven finds himself hopelessly tangled in a marriage that's equal parts political disaster, royal power struggle, and slow-burning attraction.
Because somewhere between the petty arguments, midnight demands, and stolen glances... Prince Wonwoo is stealing more than Mingyu's authority - he's stealing his heart.
