During a recent episode of Kakao TV's 'Mu:Talk Live', MAMAMOO's Hwa Sa caused laughter by confessing that the show's host Highlight's Yoseob is one of her favorite memes!

On this day, the members had a chance to go around and share some of the "TMI" with viewers and with host Yoseob. Hwa Sa then said, "This is very much a 'TMI'. There this meme that is one of my favorite memes of all time, and it is of [Yoseob] sunbaenim."

Yoseob immediately seemed to know what she was talking about, as he commented, "Is it by chance, the 'Emotional Boss' one?"

Hwa Sa nodded excitedly as she continued, "I'm so glad to meet you in person after meeting you through the meme for such a long time."

Fellow member Moon Byul also chimed in with, "I've always wanted to ask, why did you make that expression?"

Yoseob answered, "Actually, I had no idea that I made such an 'emotional' expression until several years afterward. I must have just been suuuper ticked that day." The MAMAMOO members also agreed, "That [program's] recording is extremely tiring." 

Furthermore, MAMAMOO's Whee In shared as her "TMI" of the day, "When I was in middle school, I was a really big fan of [Yoseob] sunbaenim. So I'm so glad I had a chance to meet you today."
