TWICE member, Dahyun, has just dropped a very sweet surprise for all of her ONCE’s! The singer shared a vocal and piano cover of her group’s track, “Promise,” which is featured on TWICE’s third Japanese studio album title, “Perfect World,” released last year. Dahyun, known for her bright and bubbly personality, showed a more low-key yet ethereal vibe in the newest video, making fans’ love for her grow even more! Dahyun shared a short message at the end of the video stating, “‘Promise’ is one of my favorite songs from TWICE albums, I love the piano part in this song so much, so I wanted to play it for you. I practiced it while thinking of you, ONCE!” We love how genuine Dahyun is and that she isn’t shy to show how much love she has for her fans! Currently, TWICE is gearing up for their world tour as they’ll be making their way to the U.S. within the next week. They will also be celebrating their 5th Japan debut anniversary in a major way – you can read all about that here. In the meantime, check out Dahyun’s cover of “Promise” down below!
