멍청이(twit) is the solo debut song by MAMAMOO’s HWASA, co-produced by MAMAMOO’s frequent collaborators Kim Do-hoon and Park Woo-sang.

The track is dreamy and mysterious, rather than sexy or friendly accompanied by addictive melodies and enchanting signature voice of HWASA.

“Twit” refers to a “mongcheong” i.e. a fool. HWASA calls herself and her lover a twit for not being able to take care of a loved one.
