Long considered an underrated vocalist in K-pop superstar outfit Girls' Generation, Seohyun makes her official solo debut with a mini album that shows her versatility when it comes to crafting bubblegum-pop confections. While title track "Don't Say No" sees her channeling the R&B-pop of Ariana Grande's early career, Seohyun also embraces dark trap beats on "Magic," charms with the acoustic midtempo "Lonely Love," and croons her way into tropical house with the duet "Hello," featuring equally smooth vocals from Eric Nam.
