The episode featured the couple on their first couple vacation to Nami Island. While talking to each other on a sight seeing trip, Leeteuk randomly found out that Kang Sora had recently met up with a man before a trip to Paris, France.
The ‘secret man’ ended up being none other than fellow Super Junior member Sungmin. In a fit of jealousy, Leeteuk immediately called up Sungmin on the spot to hear the truth. After confirming that they had indeed met up, Leeteuk said to the phone in a fit of blind jealousy, “I hope your musical fails!”
