30-year-old Kamata Rinko is single and a struggling scriptwriter. She has no boyfriend and keeps having night outs at drinking spots with her girlfriends Kaori and Koyuki. “If I become beautiful, a better guy will appear!” “If we grow to like each other, we can get married!” They will not stop talking about these hypothetical questions. Then a younger, handsome, golden-haired guy suddenly utters, “These “what if” women!” and the trio have to face the harsh reality that they are no longer girls. Rinko enters her 30s while still immature, seeking happiness and struggling with romance and work.
