Although B2ST has withdrawn from the music scene in order to enjoy their well-deserved vacation, they've recently unveiled their OST contribution for the upcoming drama, "My Princess"! The bright love song complements the romantic drama perfectly, as one can easily imagine the blossoming love story between a spoiled heir (Song Seung Hun) and a stingy, yet naive college student (Kim Tae Hee). Check out B2ST's "Because of You" below! Thanks to everyone who sent in a tip!
