Breve introdução: A Joseon prince, framed and drowned, wakes up six hundred years later in a modern Seoul apartment. Soo Hyun, a no-nonsense TV producer, is stunned by this time-traveling houseguest. With rent doubling and bills piling up, she makes him an offer: help her earn money, and he can stay. What follows is an unlikely cohabitation, full of comedy, cultural clashes, and growing affection. Because even across six centuries, destiny has a way of writing its own love story.
