Taeyeon's new OST single is out now!

On May 8 KST, the Girls' Generation member released "By My Side," the sixth OST single for the tvN drama 'Our Blues.'

The single begins with a calming acoustic guitar accompaniment, slowly building up to an orchestra toward the end. The emotion of the instrumental is enhanced by Taeyeon's pure vocal tone as she sings about having to let go of a love one held onto for a long time. The music video for "By My Side" follows the storyline of characters Dongseok and Seona, played by Lee Byung Hun and Shin Min Ah.
