MAMAMOO's Moon Byul has revealed a dramatic new teaser for '6equence'.

In this poster, Moon Byul poses inside what appears to be a hospital, symbolically expressing the grief that comes from love. Titled 'LUNATIC', the poster has many handwritten messages and a heart embedded inside the word. The quote at the top reads: "I cry and the I laugh, as if I am crazy".

Moon Byul's 3rd mini album '6equence' will be released on January 19 KST. What do you think of the concept?
