An invention that grants people immortality has burst onto the scene. The catch... is that you have to become a girl!
However, as she gradually learns more about her body, the girl discovers that immortality, like pregnancy, is something a woman can't achieve alone.
Why do truck drivers keep taking jobs to help people change sex? Why do girls wake up in the middle of the night in boys' dormitories? Behind it all, is this the degradation of human nature or the corruption of morality?
(PS: Near future, not pure romance, dark tone.)
