While November 11 is known by many as the popular Pepero Day, the date also marks South Korea's Disabled Persons Day. BTOB and their fan prepared the live clip to celebrate the holiday, with all of the BTOB members learning the sign language motions for the chorus of "Missing You" to perform it while they sang. 

It's an absolutely breathtaking live performance! Watch it below, and happy Korean Disabled Persons Day!
