What happens when Kim Junsu find out that his girlfriend is pregnant? Of course he has to take responsibility, but what about his career, he can't just leave everything behind. He also doesn't want to tell anyone, especially the other members because he's afraid it's going to affect them. And so he decides to beg his twin sister for help to be him for a few days, until he can figure things out.

But what exactly happens when Junsu's twin sister, Minah start living under the same roof as the other members? Will she fall in love with all of them or only one?
