The audience members even danced the "Mr. Ambiguous" dance along with the girls. The girls even sang Stooshe's "Love Me" as their encore song because of the hot response. 

The mini concert was for the girls to see their popularity for themselves, as well as to meet their fans for the first time after debut. MAMAMOO said, "It was a chance for us to feel how many fans cheered for us and loved us. Of course, there are people who don't know MAMAMOO yet, but we'll work even harder to become a MAMAMOO that everyone can enjoy."

Their label WA Entertainment said, "We thank everyone who was with MAMAMOO and enjoyed the guerrilla concert. Since the Hongdae guerrilla concert got such a good response, we're planning more in the future."
