During MAMAMOO's previous guest appearance on 'Weekly Idol', Solar expressed the wish to hang out with same-age idol friends A Pink's Chorong and BTOB's Changsub.
On the March 7 airing, Solar gave an update and said, "I didn't think it would become such hot issue" and shared the three hung out and ate together in Gangnam after the episode broadcasted. She stated, "I didn't know it was expensive but Changsub paid for it all."
Hearing this, Moon Byul mentioned the '92 club' and said, "The members are BTS' Jin, VIXX's Ken, B1A4's Sandeul, EXID's Hani, and me. I think we meet pretty often. We drink together sometimes and we love 'Escape the Room' cafes so we go there often."
