Singer Bang Yedam and ‘aespa’s Winter heightened anticipation for their new song with a sweet yet subtly complex atmosphere.

Bang Yedam released four duet concept photos for the new digital single ‘Officially Cool’, sung together with Winter, on his official SNS account at midnight on the 28th.

The two are seated side by side with a single chair between them, facing each other. There’s a slightly awkward air between them, filled with complex emotions.

In another photo, they’re holding a cake with the phrase ‘Best Friends’ written on it, looking at the camera with cool expressions, adding to the intrigue.

‘Officially Cool’ is the first duet song by Bang Yedam and Winter, harmoniously blending their emotive voices. Hit composer Kenzie took charge of the production.

Meanwhile, Bang Yedam will release ‘Officially Cool’, his first duet song with Winter, on various music sites at 6 PM next month on the 2nd.
