Choi Sang-yeop, the vocalist of the band LUCY, lends his voice to the OST for the Genie TV original drama 'Idol: The Coup' with the track 'Echo,' released today, the 16th, at 6 PM KST on various music platforms.

'Echo' is a song that combines a catchy, addictive melody that lingers in your ears with heartfelt lyrics that stir emotions.

The chorus, "I'll run even if I'm out of breath," captures the vibrant energy of youth yearning to rush forward, leaving a sense of fresh empathy and a lasting impression with Choi Sang-yeop's signature pure and clean tone.

'Idol: The Coup' is a mystery legal romance about top lawyer Maeng Se-na (played by Choi Soo-young), who boasts ultimate fan instincts, taking on the case of her favorite star Do Ra-ik (played by Kim Jae-young), who has been accused of murder. The drama is set to premiere on Genie TV and ENA on the 22nd. Music director Park Se-jun, known for hit OSTs like 'Little Women,' 'Vincenzo,' and 'Hotel Del Luna,' participated in this OST, promising a track that perfectly complements the drama's mysterious yet romantic atmosphere.

Choi Sang-yeop has solidified his reputation as an 'OST master across genres' by participating in numerous popular webtoon and drama OSTs this year, including 'HALLEY' for 'Spirit Fingers.' 'Echo' is expected to become another representative OST that guides the emotional arc of the drama, following his consistent requests and expanding his standing as a singer.

Fans are celebrating the release, commenting, 'Choi Sang-yeop's voice perfectly fits the drama,' 'I felt fluttery just listening to the OST,' and 'I'm looking forward to the drama.'
