DJ Nam Hee Suk first said, "I heard the member who acts cool around girl groups is Sandeul." To this, Jinyoung jokingly responded, "Not act cool, but he tends to overreact."

CNU�added, "There's one thing we're upset about. Everyone has to standby during end-of-the-year events where a lot of artists gather. We stay together, but Sandeul is always busy. He's always busy visiting this and that group, so that's a�bit upsetting."

Sandeul explained, "You might misunderstand, but it's not girl groups [that I visit]. I have a lot of groups that I'm close with," but CNU persisted, "Including girl groups".�

Nam Hee Suk then asked Sandeul to name some of the groups he's close with, and Sandeul answered, "There's VIXX, BTOB, BTS, as well as EXID and MAMAMOO. They're my friends so I go around to say hi. I don't get to meet them often, so I tend to go greet them at events like those."
