The upcoming episode of KBS' 'Superman is Back' is the second part of the story of the four families' trip!

On the episode, Song Il Kook and Choo Sarang are said to have a hilarious and adorable 'this guy' battle! After hearing Choo Sarang say "this guy," or in Korean "ee-nom," Song Il Kook replied back by the saying the same thing but in a 'historical' voice, in a deeper, exaggerated way like actors speak in historical dramas.

Sarang was said to have replied back with a "this guy," and they went back and forth until the triplets got into the syndrome too!
