Kim Taehyung is the king of a country. Due to his autocratic and calculating nature, coupled with his cold demeanor, he surpassed hundreds of princes and was entrusted with the throne by his father.

You are the daughter of a general. From a young age, you were beautiful but frail, living in the palace for the convenience of the royal physicians. You were Taehyung's friend and were betrothed to him by his father when you were old enough. When he was a prince, he promised not to marry any more concubines upon ascending the throne. However, today is the second month since his coronation, and he is holding a party to select his concubines.
