IU and Byeon Woo Seok Wedding Invitation Photos Released for 21st Century Grand Prince’s Wife

Disney+ Korea released original IU and Byeon Woo Seok wedding invitation photos on April 28, 2026, expanding on promotional material tied to MBC’s Friday-Saturday drama 21st Century Grand Prince’s Wife. The images show the actors as Sung Hee Joo and Grand Prince Lee An, the drama characters whose wedding setup has become part of the show’s current storyline.¹

The release followed an earlier invitation-themed post connected to a public proposal scene in the series, in which Lee An proposes to Sung Hee Joo. Multiple Korean entertainment outlets reported that the newly posted images were the original photos used for the invitation content, rather than a separate real-life announcement involving the actors.²

Original Wedding-Invitation Photos Posted by Disney+ Korea

OSEN reported that Disney+ Korea uploaded several original wedding-invitation photos through its official account on April 28, 2026. The photos were presented as invitation images for Sung Hee Joo, played by IU, and Grand Prince Lee An, played by Byeon Woo Seok, as the characters move toward marriage in the drama.¹

Newsen also described the release as a follow-up to the response to previously shared invitation images, noting that the newly released photos featured affectionate two-shots of the two actors in character.³ JoyNews24 reported that one of the photos showed IU and Byeon Woo Seok holding hands and smiling at each other, while the earlier invitation image included the phrase “We are getting married.”⁴

The invitation text itself was reported by Seoul Shinmun as reading, in translation, “We are getting married. Bride Sung Hee Joo ♥ Groom Grand Prince Lee An.” The wording identifies the invitation as a drama-related item for the characters, not an actual celebrity wedding notice.⁵

Disney+ Korea’s official social caption was also cited in Korean reports. OSEN quoted the platform as saying, in translation, that Disney+ was “more sincere about excitement than anyone” and was releasing the “fairy-tale-like original invitation” in response to a strong reaction.¹ Ilgan Sports separately reported another official caption connected to the invitation content: “At this moment celebrated by the whole country, we reveal the congratulatory message.”²

Linked to the Proposal Storyline in 21st Century Grand Prince’s Wife

The invitation photos are tied to 21st Century Grand Prince’s Wife, an MBC Friday-Saturday drama starring IU and Byeon Woo Seok. Reports identified IU’s character as Sung Hee Joo and Byeon Woo Seok’s character as Grand Prince Lee An, whose relationship is central to the invitation-themed promotional material.³

Ilgan Sports reported that the original images released by Disney+ Korea were connected to content unveiled the previous day and to the scene in which Grand Prince Lee An publicly proposed to Sung Hee Joo.² Insight likewise reported that the invitation image posted on April 27, 2026, reflected the characters’ in-drama marriage setup and followed the recent broadcast proposal scene.⁶

The sequence of releases gives the photos a clear promotional context. On April 27, Disney+ Korea shared invitation-themed content for the drama; on April 28, the platform followed with the original photos used for that content, according to the Korean reports.⁶² The articles do not describe the photos as evidence of a real engagement or wedding between IU and Byeon Woo Seok outside the drama.

The use of wedding-invitation imagery appears to have extended the drama’s on-screen plot into official social media promotion. The reported captions and invitation wording refer to Sung Hee Joo and Grand Prince Lee An, and the outlets consistently framed the release around 21st Century Grand Prince’s Wife rather than the actors’ private lives.¹⁵

Broadcast and Ratings Context

21st Century Grand Prince’s Wife airs on MBC on Fridays and Saturdays at 9:50 p.m. and is also available for streaming on Disney+, Ilgan Sports reported.² The timing of the wedding-invitation photo release came after the drama’s sixth episode aired on April 25, 2026.

OSEN and Seoul Shinmun both reported that the April 25 sixth episode recorded an 11.2% nationwide rating based on Nielsen Korea figures.¹⁵ JoyNews24 described the same 11.2% figure as the drama’s own highest rating.⁴

That ratings context formed part of the coverage around the invitation photos, with reports presenting the image release as a response to interest in the drama’s proposal and wedding storyline. The available source material does not provide further details about the next episode’s plot, any confirmed wedding episode date, or additional promotional releases beyond the April 27 and April 28 invitation-related posts.

21st Century Grand Prince’s Wife wedding invitation photos release concept

The IU and Byeon Woo Seok wedding invitation photos are therefore best understood as official drama promotion for 21st Century Grand Prince’s Wife, centered on Sung Hee Joo and Grand Prince Lee An’s fictional marriage storyline. Based on the available reports, Disney+ Korea released the original invitation photos on April 28, 2026, after earlier invitation content and following the drama’s proposal sequence.
