September seems to be gearing up to be quite the comeback month, at least as to those groups and artists on my personal radar. The dance powerhouse quintet, A.C.E is one of those groups. Even though this is the group’s fourth mini album, it is my first A.C.E comeback. The anticipation level was high and when they dropped the title track to their HJZM:The Butterfly Phantasy mini album, I wasn’t sure if 도깨비 (Favorite Boys), was supposed to shock or seduce me. Confession: it did both.
