The great royal couple IU, Byeon Woo-seok shake 21st-century Korea with an irresistible charm.

The main teaser video announcing the beginning of the identity-breaking romance between Seong Hee-ju (IU) and Grand Prince Ian (Byeon Woo-seok) from MBC's new Friday-Saturday drama Perfect Crown (written by Yoo Ji-won / directed by Park Joon-hwa, Bae Hee-young / planning by Kang Dae-seon / produced by MBC, Kakao Entertainment), which will premiere on Apr. 10 (Fri) at 9:40 p.m., was released.

The released teaser video begins with Seong Hee-ju's confident smile as she proposes, saying to Grand Prince Ian, "Marry me." Grand Prince Ian accepts, saying, "I cannot refuse," in response to Seong Hee-ju's bold self-promotion, who not only has education, grit and ability but is also a commoner with no relatives by marriage to intervene.

At Grand Prince Ian's command to "prepare to become a grand consort," Seong Hee-ju and Grand Prince Ian spend romantic time together. They walk proudly hand in hand under pouring spotlights, and inside the banquet hall they waltz as if enjoying people's gazes, creating a rather couple-like atmosphere.

However, forces opposing the marriage of Seong Hee-ju and Grand Prince Ian also emerge, raising the tension. Prime minister Min Jung-woo (Noh Sang Hyun) pleads with Grand Prince Ian to push Seong Hee-ju far from the royal family, and the queen dowager Yoon I-rang (Gong Seung-yeon) urges Min Jung-woo to exercise a veto over the couple's marriage.

As the difficult journey is expected because Min Jung-woo and Yoon I-rang dominate politics and the royal family respectively and oppose the marriage, Seong Hee-ju and Grand Prince Ian's faces show a slightly different flutter from before as they look at each other. Despite all the checks and obstacles, the romance of Seong Hee-ju and Grand Prince Ian, who will show a strong married-couple chemistry, is anticipated.

Through its main teaser video, Perfect Crown foreshadows the inevitable confrontation between Seong Hee-ju and Grand Prince Ian, who chose marriage as a means to overcome their fates, and Min Jung-woo and Yoon I-rang, who stand on the opposite side. It raises the question of whether Seong Hee-ju and Grand Prince Ian can marry safely against opposition from the executive branch and the royal family.

Meanwhile, even before its first broadcast, Perfect Crown has drawn strong buzz befitting a highly anticipated work of the first half of 2026 by ranking first in community response and second in SNS in the TV-OTT drama category overall, placing second in Good Data Corporation's FUNdex buzz rankings for the third week of Mar. 2026.

Meanwhile, Perfect Crown is a status-breaking romance set in 21st-century constitutional monarchy Korea about a woman who has everything as a chaebol but is annoyed because her status is that of a commoner, and a sad man who is the king's son but has nothing, and their fate-seeking journey.
