On November 14 KST, Disney Plus Korea announced that its original series 'Soundtrack #2' is set to release on December 6, unveiling an intriguing poster and a teaser trailer to stir the viewers' excitement.

The released teaser poster showcases a scene at a bus stop, featuring three main characters against an emotionally evocative illustration. Within this setting, we see Noh Sang Hyun, looking classy in a business suit, and Son Jeong Hyuk, drawing attention with his youthful style and shy demeanor. Both actors represent contrastive appeal — Noh Sang Hyun embodying the role of successful CEO Ji Soo Ho, and Son Jeong Hyuk playing the handsome singer-songwriter Kei. The poster raises expectations for their storylines, leaving viewers wondering about the future of these two characters.

Geum Sae Rok, with her dazzling smile, adds another layer of intrigue to the poster. She portrays the character Do Hyeon Seo, a pragmatic individual struggling with the realities of work and dating. The poster aptly visualizes Hyeon Seo's dilemma, torn between Soo Ho, her ex who suddenly reappears, and Kei, a straightforward guy who captures her attention. 

In the released teaser trailer, an unexpected reunion takes place between Hyun Seo and Soo Ho, four years after their separation. This is further complicated by the sudden appearance of a new character, Kei, adding an extra layer of fun and unpredictability.
