New behind-the-scenes photos of BTOB Sungjae from the filming of 'Who Are You? School 2015' are released.

This time, Sungjae filmed a rather difficult scene which required him harness and crane. This filming took place in a hospital in Gyeonggi-do, wherein Sungjae is seen hanging loosely in the air while sitting in a piece of wood and bundled himself with ropes.

According to Sungjae, he was initially thrilled to do the scene as it looked so exciting and fun just like that of a bungee jumping but eventually took back his words. He described that it wasn't fun at all as he was shook by the wind when he was hanging in the air. He also asked viewers to anticipate the drama as it took a lot of effort for unconventional scenes.

It seems like our troublemaker is having an hospital escape for this scene. Are you thrilled for its first episode on 27th?
