Actors Lee Yoo-mi and Noh Sang-hyun are lending their presence to the debut of SEVENTEEN's new unit DK × Seungkwan.

On January 6, Pledis Entertainment unveiled eight cinematic posters for the title track "Blue" from DK × Seungkwan's first mini album via SEVENTEEN's official SNS channels.

Both actors appear in the music video, which is produced in a dramatized format. The storyline portrays a love between two people moving at different emotional paces, capturing subtle shifts in distance and feeling.

Their on-screen chemistry has heightened anticipation for the full music video, drawing curiosity about how their exchanged glances eventually drift apart.

"Blue" depicts the moment when emotional depth and timing slowly fall out of sync. Paired with DK × Seungkwan's vocals, the track delivers the essence of a winter ballad.

Meanwhile, DK × Seungkwan will release their new song "Soya Song" on January 12 at 6 p.m., weaving an emotional narrative that captures every moment between meeting and parting.
