The main teaser for the drama introduces the beginning of a romance that defies social status between Seong Hee-joo (played by IU) and Lee An Grand Prince (played by Byeon Woo-seok).
As Lee An Grand Prince instructs, "Prepare to become the Grand Prince's wife," the couple shares romantic moments, walking hand in hand under the spotlight and dancing a waltz at a banquet, exuding a genuine couple-like atmosphere.
However, opposition to their marriage arises, heightening the tension.
