SEE ALSO: SPOILER K-netizens react to the ending of 'Queen of Tears'

During the filming for the episode, Lee Hwi Jae took the twins to a cat cafe to help them feel comfortable around animals. Instead of getting scared by the cats that were the same size as them, Suh Un and Suh Joon opened their eyes wide in interest and began petting them. With a toy stick, they caught the cats' interest, and a swarm of cats started to surround them with the twins seeming to enjoy themselves very much.

Stay tuned for their interaction with cats this Sunday at 4:50 PM KST!
