MooMoos seem to be giving up on their various speculations on what could be Mamamoo's comeback concept this time.

Based on the teaser images released so far, a single concept can't be drawn out. The girls started off teasing with a nostalgic and mysterious theme, then retro, and a rather sophisticated yet innocent image.

However, the latest teaser image for 'Melting Time' reveals the girls wearing orange safety uniforms looking all adorable. Fans comment, "Ah I'm going crazy with these photos. I'll just wait for the comeback!","I give up guessing the concept.","Really? What concept is it this time?"

If you also have no clue, let's just anticipate their new track preview video on 11th and album on 26th.
