DAY6 Young K Brings His Signature Vocals to My Royal Nemesis OST Season of Us

Young K of DAY6 is stepping into the spotlight with a new OST track that promises to be one of the more distinctive K-drama songs of the season. Season of Us (다시 돌아온 계절), his contribution to the SBS Friday-Saturday drama My Royal Nemesis (멋진 신세계), drops on May 16, 2026 at 6 PM KST — and the early descriptions suggest a track built specifically around what makes Young K unique as a vocalist.

The song serves as OST Part 2 for My Royal Nemesis, the ongoing SBS drama that follows the reincarnation romance between Shin Seo-ri (Im Ji-yeon) and Cha Se-gye (Heo Nam-jun). The two characters share a past-life connection that pulls them back together in the present day, and the OST brief for Season of Us was to capture exactly that feeling: the overwhelming emotion of recognizing someone across lifetimes, and the exhilarating rush of falling for them all over again.

What the Song Sounds Like

Season of Us is described as a medium-tempo synth-pop track — a genre that sits at the intersection of electronic texture and melodic warmth, often used in K-dramas to score the emotional peaks of romantic storylines. The song is structured around the moment two destined lovers first recognize each other in the present, with the music designed to carry both the weight of their shared history and the breathless energy of a new beginning.

What distinguishes this track, according to advance descriptions, is the specific way it draws on Young K distinctive vocal character. He is known for a voice that is simultaneously bright and emotionally weighty — a clear, far-reaching tone that can carry vulnerability without losing power. In a synth-pop context, that kind of voice provides an emotional anchor for the electronic instrumentation, giving the track a human center that can connect with drama viewers even in their most invested moments.

Young K has consistently demonstrated this quality across his work with DAY6, a four-member JYP Entertainment band that occupies a particular and somewhat unusual space in the K-pop landscape: a genuine band with live instrumentation, regular album releases, and a dedicated fan base that values musicality alongside performance. As the group bassist and one of its primary songwriters, Young K has contributed to a discography that includes multiple critically appreciated albums and a reputation for emotional sincerity that distinguishes DAY6 from more performance-focused idol groups.

A Collaboration Built on Real Friendship

There is a personal dimension to this particular OST. Young K and My Royal Nemesis lead actor Heo Nam-jun were born the same year, and the two have maintained a friendship through overlapping professional circles. When Young K agreed to contribute to the drama soundtrack, it was in part a direct act of support for his same-age friend — the kind of gesture that often produces something more genuine than a purely contractual OST arrangement. Whether or not that background is audible in the final recording, it adds context to the collaboration that fans of both the drama and DAY6 have found meaningful.

Heo Nam-jun has been generating attention for his performance in My Royal Nemesis, a drama whose central premise — two people reconnecting across multiple lifetimes — requires a certain kind of emotional specificity that can easily tip into melodrama without the right performance grounding it. Early viewer response has been warm, and the drama has attracted an audience interested in both the reincarnation romance genre and the particular chemistry between Im Ji-yeon and Heo Nam-jun.

Young K in 2026

For DAY6 fans, the appearance of Young K on a major SBS drama soundtrack is a welcome signal of sustained activity from one of the group most visible members. DAY6 has been operating in a dispersed fashion in recent years as members have navigated military service and individual schedules, but Young K has maintained a presence through solo releases and collaborative projects. His previous OST contributions have been well-received, and his vocal approach — which tends toward emotional directness rather than technical showmanship — translates particularly well to the drama format, where the goal is to deepen a scene rather than demand attention for itself.

The release of Season of Us also arrives at a point when K-drama OST culture is receiving more international attention than ever before. As global streaming platforms have expanded the reach of Korean dramas, their soundtracks have followed, with certain OST tracks accumulating millions of streams on platforms like Spotify and Apple Music from listeners who may never have watched the drama that inspired them. For a vocalist like Young K, whose work with DAY6 already has an established international following, an OST release on a high-profile SBS drama carries potentially significant reach beyond the domestic Korean audience.

Season of Us (다시 돌아온 계절) by Young K of DAY6 releases on May 16, 2026 at 6 PM KST. My Royal Nemesis airs on SBS every Friday and Saturday.
