Why Fans Thought TXT's Yeonjun Showed Up With His Ex

A simple outing between two entertainment industry colleagues turned into one of the week's most talked-about moments online — and it all came down to context that most casual observers didn't have.

A video clip circulating on social media showed TXT's Yeonjun stepping out at the VIP premiere of the upcoming Korean horror film Salmokji: Whispering Water at Lotte Cinema in Seoul, accompanied by actress Yang Hye Ji. The clip spread rapidly, with some viewers puzzling over the pair being described as "ex-partners" attending the event together. What followed was a wave of confused — and then deeply amused — fan reactions as the truth quickly came out.

A Drama Connection Five Years in the Making

To understand why this moment went viral, you have to go back to January 2021. That month, Yeonjun made a cameo appearance in the JTBC teen romance drama Live On, starring opposite Yang Hye Ji, who played the female lead Ji So Hyun. Yeonjun's character, Kim Jin Woo, was Ji So Hyun's ex-boyfriend from middle school — someone she unexpectedly crosses paths with again at a library for the first time in three years.

The cameo created significant buzz at the time. Yeonjun had only been an idol for about two years, and stepping in front of a drama camera was new territory. By all accounts, he handled it with remarkable composure. The director reportedly praised him after he completed his first scene in a single take, earning him the informal title of "acting god" among fans.

Yeonjun himself was candid about the experience afterward. "I did want to try acting, but since it hasn't been that long since our debut, I didn't expect too much," he said. "So when I heard I'd been offered a role, I was really surprised." After the episode aired, "Actor Yeonjun" trended worldwide — a clear sign that audiences had taken notice.

Five years later, seeing the two reunited in public at a film premiere was enough to send fans into a brief spiral of confusion before the explanation surfaced.

The Internet's Reaction Was Priceless

The best part of the whole incident was how the online community processed it in real time. Social media users initially encountered posts framing the premiere appearance as Yeonjun attending with his "ex-girlfriend," with no immediate clarification about what that actually meant.

Once the context became clear — that the "ex" relationship was entirely fictional, a character dynamic from a 2021 drama — the reaction shifted from confusion to genuine delight. One commenter summed it up best: "those who don't know may have had a heart attack." Another noted: "I thought you were deadass getting away with spreading rumors until I realized this was about the kdrama."

Several fans admitted they had to reread posts multiple times before connecting the dots. That collective moment of "oh wait, it's from the drama" became its own layer of the viral story, with fans appreciating how perfectly the real-life reunion mirrored the kind of playful dramatic irony that K-dramas love to serve up.

The Film That Brought Them Together

The occasion for their reunion was the VIP premiere of Salmokji: Whispering Water, a Korean horror film scheduled for theatrical release on April 8, 2026. Distributed by Showbox and directed by Lee Sang-min, the film follows a road-view filming crew dispatched to a remote reservoir to reshoot footage previously deemed unusable due to unexplained visual distortions. What begins as a routine technical job soon turns into something far more unsettling as the crew begins encountering figures in their recordings and uncovers a past incident linked to the reservoir that was never fully resolved.

The film stars Kim Hye-yoon and Lee Jong-won in the lead roles and has already attracted attention on the international circuit, with Showbox introducing it to buyers at the European Film Market. Industry observers have been watching it closely as a potential catalyst for renewed interest in Korean low-budget horror — a genre that has historically punched above its weight in terms of global audience reach.

Yeonjun's Growing Profile Beyond Music

The premiere appearance served as a reminder that Yeonjun has been building a quietly impressive parallel career alongside his work with TXT. Beyond the 2021 Live On cameo, he returned to drama acting in May 2025 with an appearance in the popular tvN medical drama Resident Playbook. He appeared in episode nine alongside TXT member Soobin, with the two playing members of a fictional idol group called HI-BOYZ. The episode aired on May 10, 2025.

Outside of drama work, Yeonjun has been establishing himself as one of K-pop's more versatile solo performers. He released his debut EP No Labels: Part 01 in November 2025, with the title track "Talk to You" charting on the Billboard 200 and selling over 500,000 copies. He took the track to NBC's The Kelly Clarkson Show, marking a significant step in his international visibility.

Earlier this month, he released "Make It Count," a collaboration with Becky G and Mike Towers produced by two-time Grammy winner Tainy. The track was part of the official 2026 World Baseball Classic soundtrack — a first for the tournament — with Yeonjun becoming the first and only Korean artist included in the project. He also walked the runway for Miu Miu at Paris Fashion Week on March 10, reinforcing his growing presence in global fashion circles.

What's Coming Next

The timing of this viral moment is notable: TXT's next chapter is just around the corner. The group's 8th mini-album, titled 7TH YEAR: A Moment of Stillness in the Thorns, is set for release on April 13, 2026. Pre-orders opened on March 3, and the comeback showcase is scheduled for the same day at Korea University's Hwajeong Gymnasium in Seoul, with global streaming available for international fans.

The album arrives following TXT's three-night anniversary concert at KSPO Dome in Seoul in late February and early March, where approximately 33,000 fans attended each night. On the closing night, the group revealed the comeback trailer for the new album — and Yeonjun's solo performance of "Talk to You" became one of the most-talked-about moments of the entire run. "It felt like watching a solo concert," one fan wrote. "You can tell he's enjoying every moment."

All five members — Soobin, Yeonjun, Beomgyu, Taehyun, and Hueningkai — renewed their contracts with BIGHIT MUSIC in August 2025, making the upcoming release the group's first full album drop since that milestone. For MOA, TXT's dedicated fanbase, the energy heading into April is high.

And somewhere in the middle of all that momentum, Yeonjun took time to show up at a horror film premiere with a former drama co-star — creating a viral moment that reminded fans why his cross-genre presence keeps on growing.
