If you're a K-pop enthusiast, chances are you've probably heard of Mnet's competition program series "Road to Kingdom."

For followers of the franchise, it's hard to miss the name, ONEUS, a five-piece boy band that has appeared not once, but twice in its consecutive seasons — the first in 2020 and the latest, "Road to Kingdom: Ace of Ace," which aired its finale in November 2024.

While the group finished fourth in its first appearance, edged out by seasoned industry seniors, the group climbed to second place four years later. The result wasn't a victory, but the five members of ONEUS saw it as a testament to their growth.

"In the first season, our goal was simply to do our best and present great performances. But this time, our aim was to win. Although we didn't achieve that, just being able to set a higher goal made us feel that we had grown significantly," Keonhee told The Korea Times during an interview at a cafe in Seoul's Gwangjin District, Tuesday.

"Creating memorable stages was a given, but realizing we could even aim for victory was a testament to our development as a group ... That's why finishing as the runner-up feels less like a loss and more like a milestone."

While narrowly missing the top spot was bittersweet, the group said the experience rekindled meaningful connections.

"When we received the runner-up result, those around us seemed even more disappointed than we were," Keonhee said. "Staff from our agency, of course, but especially our longtime fans who have always supported us. It made us realize how well we've done over the past six years and how many people truly cherish us."

As a gesture of gratitude, ONEUS decided to dedicate its next project entirely to its fans. On Tuesday, the group released a special album titled "Dear.M," which features rerecorded versions of its previous title tracks alongside brand-new songs.

"It's already been six years since our debut and this album is a gift to the fans who have supported us throughout this journey," Hwanwoong said. "I think it truly reflects our heartfelt gratitude and the love we have for them."

The new album's lead single, "IKUK," was first performed during "Road to Kingdom: Ace of Ace." Known for their distinctive visual storytelling — from portraying merman princes to fictional monarchs — the members emphasized the unique aesthetics of the new release.

"Over the years, we've explored various concepts and genres, but this time we're revisiting the vampire theme, a fan favorite, after several years. The difference now is that this vampire concept feels like aged wine — refined and matured," Keonhee said. "Beyond just showcasing pale skin and fangs, we also explored the emotional struggles of a monster in love with a human being. We really do hope fans look forward to it."

Six years into its career, ONEUS is now facing a critical hurdle: the seven-year mark, a milestone often seen as a turning point for idol groups due to contract expirations. Additionally, Seoho, the group's eldest member, is preparing to begin his mandatory military service this year, raising questions about the group's future.

Regarding the uncertainties, however, the ONEUS members remained resolute.

"While we can't reveal any specific plans just yet, one thing we can confidently say is that we are moving forward with the intention of protecting ONEUS until the end," Keonhee said, addressing the worries. "Ultimately, we want to preserve this team we love so much and keep performing. If anyone is worried, please don't be."

Seoho echoed this sentiment, expressing his readiness for military service. "It's my duty as a citizen and I'm fully prepared to fulfill it," he said. "I'll do my best and return stronger. I look forward to showing you how much I've grown when I return."
