Members of NCT, TAEYONG and HAECHAN, are set to release their first-ever duet since debut.

On March 29 at 6 PM (KST), the duo will unveil "Bitter Sweet (Addiction)," an OST for the tvN weekend drama How to Become a Building Owner in Korea.

Funky House Sound Meets Addictive Hook

"Bitter Sweet (Addiction)" is a funk house track built around a groovy bassline and upbeat drum rhythms. Its repetitive chorus delivers strong hook appeal, enhancing its addictive quality.

The lyrics reflect the drama's central narrative—capturing characters who, despite harsh realities, refuse to give up and continue chasing new opportunities with resilience.

Contrasting Styles, Amplified Tension

The track highlights a clear contrast between TAEYONG's rough, textured rap and HAECHAN's bright, refreshing vocals. This dynamic interplay is expected to deepen the emotional tension of the drama.

The series follows a suspense-driven storyline centered on a struggling landlord who becomes entangled in a staged kidnapping scheme. As conflicting desires over property escalate, the plot unfolds with unpredictable twists.

"How to Become a Building Owner in Korea" airs every Saturday and Sunday at 9:10 PM (KST).
