Otoko Tomodachi Girl

Etou Shougo is a university student sharing an apartment with his male childhood friend Yoshizawa Natsuki. When Natsuki leaves to take part in a clinical trial Shougo didn\t know he would be coming back as a girl! It looks like Natsuki won\t turn back into a guy for a whole year. Rather than worrying about it pointlessly, why not have some fun with it instead?
