Who knows what MAMAMOO is up to, but shed your confusion so you can fully enjoy this beautiful new MV featuring Solar, who uses her incredibly soothing vocals to sing "I've Lived Like a Fool."

Her voice is backed simply by a piano instrumental as she tries to persuade her listeners that she's lived like a fool up to this point. �Well, any mistakes you've made, Solar, would automatically be forgiven by that voice! �Make sure you listen to the end to hear all the great notes hit by the main vocalist of MAMAMOO, and stay tuned to see what this project is really about. �And watch the video to see her cute antics!
