I thought this song didn’t quite go well with the Korean drama “Moon Lovers: Scarlet Heart Ryeo” when I first heard it. Being a historical drama, the R&B sound of 너를 위해 (or For You) seems weird in that context.
Then again, “Moon Lovers: Scarlet Heart Ryeo” isn’t entirely a historical drama since it tells of an woman who goes back in time to the Goryeo dynasty from the present.
They disbanded before I started listening to Kpop. But I would find out about SECHSKIES when they reunited 16 years after their disbandment through Korean variety show “Infinite Challenge”.
커플 (or Couple) was one of SECHSKIES’ well loved songs and they were often asked to sing it on the “Infinite Challenge” episodes documenting the run-up to their reunion concert. That’s how I got to know the song and came to like it.
