Night Cherry Blossom Trance

You better be prepared, 'cause I'll make you feel good. After being locked in a mysterious building, I ended up performing a show. Lively music, and four gorgeous dancers... among them is an arrogant-looking guy who catches my eyes. This guy took me to a secret room, fresh after the show and starts pushing himself on me! But, just when everything was getting steamy, I turn into a woman? "Huh, this is your first time doing a 'trance', " so he says. Not knowing what's going on, I find myself in the company of these four. This series is set in the world of handsome men and those transforming into women!
