Red Velvet "PSYCHO" chart rankings— mes #TeamPinky (@OH_mes2) December 23, 2019
12am KST - Realtime All-Kill
Red Velvet has achieved a Realtime All-Kill (RAK), or getting #1 on all the charts simultaneously, making them the only girl group to do so this entire year. They are now also one out of only 2 groups who got an RAK this year, alongside BTS with "Boy With Luv". This means RV is also the only SM idol group who received an RAK this year (and they remain the only SM artist that has ever achieved a PAK, with "Power Up").
