What if one night, amidst their dance performance for their fans , with the Full Moon on its peak, a magical thing happened to him and he transforms unexpectedly into a Girl?! How will Haru keep up with this drastic change he is experiencing? How will his co-members respond to this? With this surprising turn of events, will his life turn Better? Or Worse?
