If you're a Melody, you're undoubtedly going, "Oh lord, what is it this time?", because BTOB's Sungjae is the 6th member up for the group's comedic video teaser series!

What is Sungjae "missing"? Finding himself in the middle of a huge field of grass with no public restrooms for probably miles around, the idol has to resort to taking care of business in the dirt, and ends up dearly missing the oh-so common, modern toilet.

The keyword for BTOB's comeback with their 2nd album 'Brother Act' is "missing". Stay tuned for the last member Eunkwang's video teaser next, before BTOB's full return on October 16 at 6PM KST!
