On March 5, 2001, Nana Osaki and
Nana Komatsu cross paths when they both move to Tokyo
after turning 20 years old:
Nana Osaki to pursue a professional music career with
her band, Black Stones, on her own merit;
Nana Komatsu to join her friends and move in with her
boyfriend.
Despite having different personalities and ambitions, the two women
find commonalities with each other and, by coincidence, move into the
same apartment.
However, as they follow their dreams, troubles of fame and love
begin to test their friendship.
