Yuki's Unexpected Transformation

Yuki wakes up a female and is in complete shock to the unexpected transformation. For the next week, Yuki will have to continue life as a girl rather than a boy. What will happen between him and Luka? Will Yuki regain any memories during the course of this week? Not only does Yuki have to worry about Luka, but it seems like Hotsuma, Tsukomo, and Kuroto are acting weird around him.
