The idol and the veteran comedian have grown much closer now that they've recorded the show as housemates several times. On this week's broadcast, Lee Kyung Kyu was the one to wait for Sunggyu to return home from his schedules. He also cooked some unique ramen recipes for the idol, including seaweed ramen and tomato ramen. 

The two then spent some time revisiting Sunggyu's past musical script! The musical is full of classic Korean favorite songs that Lee Kyung Kyu's generation knows and loves, which got Lee Kyung Kyu singing along to Sunggyu's live vocals. The comedian quickly proved that he's no good at performing any semblance of a duet, though.
