On March 30, MAMAMOO members Solar and Moon Byul appeared as guests on Mnet's 'TMI Show'. 

On this day, Solar and Moon Byul answered various questions sent in by fans. One question asked, "If you could become any other K-Pop idol for one day, who would you choose to become?"

Solar answered without hesitation, "BTS sunbaenim."

MCs Boom and Lee Mi Joo laughed and agreed, "Me too, me too," while Boom also added on, "I want to be RM." The MC then asked Solar and Moon Byul to choose one member of BTS. 

Both MAMAMOO members answered, "J-Hope sunbaenim." Moon Byul explained, "I met him once when we had overlapping schedules, and he gave off the brightest energy, and was so kind."
