So the manga is about a guy who is supposed to dress up as a female and act in traditional plays where there are no female actors allowed. At the start he doesn't want to dress like a girl and refuses. But he ends up doing it. I cant remember but I'm pretty sure its a yaoi or shounen ai and other men fall in love with him. If anyone knows it, I'd really appreciate it
