We reported yesterday that Sojin was gearing up to release her first solo single for the "Flames of Desire" OST. Although it's a remake of Gilme's version of the song, Sojin's clear vocals lends a bittersweet strength to the ballad. A definite tearjerker if you're in the right mood. Check out the track below (and you can purchase the digital single here): Thanks to everyone who sent in the tip!
