IDOLS (RED VELVET, BAP, ASTRO, BTOB, NCT127, JBJ) REACTING TO KARD OH NANA @NCT NIGHT NIGHT PART 1

This is the opening song for NCT Night Night so the change the lyrics a bit. I'm really glad they choose OH NANA for their theme song so the guest or idols who's invited can listen to KARD song. I think most of them know KARD and they seem enjoyed the song.
