Thank you for your reaction!!! Suga is a member of the group BTS. He is incredible and has many of his own solo tracks if you're interested! He and Halsey have collaborated on two other songs previously, one with BTS and one with Suga on his solo album released under his alter ego name Agust D. The song that Halsey did with BTS is called Boy With Love and if you wanted to check out Suga's alter ego Agust D, he just released a fire track called "Haegeum." Make sure to turn on the CC's for english translation as the song is mostly in korean~! Pleasure to meet you!
