For the second episode of the show, the guests continued to solve puzzles without Ji Joo Yeon, who was eliminated last week. Heechul, Lee Yong Jin, and Han Suk Joon came across a riddle that said, "When a man and woman are in love, they do this."

Heechul responded, "This isn't a problem I can even solve. I've never loved a woman for a long time before." Han Suk Joon then guessed, "Kiss," and then made another guess that was censored out.
