The idol group B2ST filmed for KBS "Yoo Hee Yeol's Sketchbook" yesterday.

B2ST, who released their new song "Shadow" on July 19, held their first comeback stage on 'Sketchbook' and met the audience members. Son Dongwoon even revealed his piano skills.

Yoo Hee Yeol told Yoon Doojoon, "You and I have similar images," arousing laughter from everyone.

"Shadow" was written by member Yong Joonhyung with his music partner Kim Tae Joo, producing a dark, dance melody. They threw away their usual images in their music video and revealed their dark charms instead.

This episode of 'Sketchbook' will be aired on July 26.
