tvN Sets July Premiere for Guardian 10th Anniversary Special With Gong Yoo, Kim Go Eun and Yoo In Na

tvN is turning one of Korean television’s most enduring fantasy romances into a reunion event. The network has released a new teaser for Guardian: The Lonely and Great God 10th Anniversary, a special program marking a decade since the drama became a defining title for international K-drama audiences.

The special brings together Gong Yoo, Kim Go Eun and Yoo In Na as they prepare to revisit Gangneung, a city closely tied to the drama’s most memorable filming locations. Lee Dong Wook is also part of the anniversary project, although the teaser notes that prior commitments keep him from joining the first planning meetup shown in the preview.

According to the teaser report, the first episode opens with the cast gathering for the first time in a while to plan the trip. Rather than presenting the reunion as a formal retrospective, the preview leans into the relaxed chemistry among the actors. Kim Go Eun reacts with visible excitement when Yoo In Na arrives, and the two quickly fall into playful banter with Gong Yoo.

A reunion built on familiar chemistry

The teaser’s appeal comes from how casual the cast dynamic feels. Gong Yoo tries to keep the conversation organized as the group discusses the Gangneung trip, while Kim Go Eun and Yoo In Na appear more easily distracted. Their joking keeps the preview light, giving longtime fans a glimpse of the off-screen rapport that helped sustain affection for the original drama.

One moment highlighted in the report shows Gong Yoo teasing Kim Go Eun about the way she addresses him as sunbae, the Korean term often used for a senior colleague. He jokes that the title sounds respectful, but that she still makes him do everything. Kim Go Eun responds by pretending not to hear him, turning the exchange into the kind of gentle ribbing that anniversary specials often rely on.

Yoo In Na also frames the group dynamic with a warm joke, saying that even if they annoyed Gong Yoo for 100 hours, he would not get angry. That line gives the teaser its clearest tone: nostalgic, affectionate and built around the pleasure of seeing actors slip back into an easy rhythm after years away from the original production.

Why Guardian still matters

Guardian: The Lonely and Great God, widely known by many international viewers as Goblin, remains a major reference point in the global K-drama boom. Its mix of fantasy, romance, melancholy humor and memorable imagery helped make it a drama that fans continued to discuss long after its broadcast. An anniversary project gives tvN a way to acknowledge that staying power without needing to extend the fictional story itself.

The choice of Gangneung is especially important. Location-based memories are a major part of K-drama fandom, and returning to real places associated with famous scenes can make a retrospective feel more tangible. For viewers, the trip format offers more than cast interviews; it turns the program into a guided revisit of the atmosphere that made the drama recognizable.

The special also arrives at a time when reunion and anniversary programming has become a useful way for networks to reconnect older hit titles with newer audiences. Younger viewers who discovered Guardian through streaming may see the special as an entry point into the drama’s history, while original fans get a chance to watch the cast reflect on its legacy in a less scripted setting.

For the actors, the format appears designed to emphasize memory rather than promotion. The teaser does not suggest a sequel or a revival of the drama’s plot. Instead, it focuses on the cast looking back, traveling together and sharing stories from behind the scenes. That approach may be better suited to a drama whose emotional ending and visual identity are already firmly established in viewers’ minds.

Premiere details

Guardian: The Lonely and Great God 10th Anniversary is scheduled to premiere on July 4 at 9:10 p.m. KST. The first teaser positions the program as a warm, travel-centered reunion that celebrates the drama’s legacy through conversation, location memories and the cast’s familiar humor.

Whether viewers return for nostalgia, the cast interactions or the chance to revisit Gangneung through the lens of a beloved series, the special is likely to draw attention from K-drama fans who still associate Guardian with one of the genre’s most recognizable global moments.
