On the Park Jung Woon & Kim Min Woo special, Niel covered Kim Min Woo's "Friend Who's Like a Breather" along with the help of Ricky and 100%'s Rokhyun and Hyukjin. The idol singers returned to their high school days with a school uniform concept, and they even sampled elements from the Beatles famous hit "Hey Jude".

Niel said, "I've never stood on stage with just the four of us, so it was good. I was proud and touched."

Despite the amazing collaboration, it was Ben and Im Se Joon, who took the final win.
