B2ST's third unit (consisting of Hyunseung and Kikwang) finally revealed their duet track, "Let It Snow," on the afternoon of December 23rd. A part of the group's digital album, "My Story," the song follows the releases of Doojoon & Dongwoon's "When This Door Closes" and Junhyung & Yoseob's "Thanks to." As both songs are currently ranking in on major music charts, many are expecting "Let It Snow" (a sexy pop ballad) to do just as well as the two other units. Check it out below, and remember to support the artists by purchasing the music!
