SEVENTEEN’s vocal unit DK and Seungkwan is deepening anticipation for its debut release with the reveal of cinematic posters and a notable acting lineup.
On January 6, PLEDIS Entertainment shared eight cinematic posters for the title track ‘Blue’ from DK and Seungkwan’s first mini album ‘Nocturne’ via SEVENTEEN’s official SNS channels. The posters immediately drew attention not only for their film like atmosphere, but also for confirming that actors Lee Yoomi and Noh Sanghyun will appear in the upcoming music video.

A Drama-Style Music Video With Emotional Tension
The music video for ‘Blue’ has been produced in a dramatized format, visually interpreting the song’s central theme: “love moving at different paces.” Rather than relying on performance-driven imagery, the video focuses on storytelling, using restrained emotions, lingering gazes, and subtle distance to convey emotional misalignment.
Lee Yoo-mi and Noh Sang-hyun portray characters whose relationship slowly drifts apart, despite shared feelings. The newly released posters capture key emotional beats—from moments of closeness to scenes where their eyes no longer meet—building curiosity about how their story will unfold in the full video.
Fans have responded strongly to the pairing, noting the quiet but palpable chemistry suggested through the stills and expressing heightened anticipation for the narrative payoff.

‘Blue’: A Winter Ballad Built on Harmony
‘Blue’ is a ballad that captures the fragile moment when two people feel the same emotion but not with the same depth or timing. DK and Seungkwan’s layered vocal harmonies form the emotional backbone of the track, amplifying the sense of longing and restraint rather than dramatic heartbreak.
By pairing the song with a cinematic narrative, the unit underscores its intention to let emotion lead the experience, aligning visuals and sound into a cohesive story.

A Unit Focused on Storytelling
DK and Seungkwan’s debut mini album ‘Nocturne’ (Korean title: ‘소야곡’, meaning “a love song sung at night”) centers on the emotional spectrum between meeting and parting. Across the album, the duo explores love in its quietest, most vulnerable moments—where words fall short and emotions linger.
Industry observers note that choosing a drama-style music video with established actors signals confidence in the music’s emotional weight, allowing the story to unfold without relying on spectacle.
Release Date
DK and Seungkwan will release ‘Nocturne’ on January 12 at 6 p.m. KST, with ‘Blue’ serving as the album’s title track.
