A popular manga, anime and now movie. The movie was very good and I couldn't help but love the main characters. The actors portray their characters very well. I recommend this movie highly! The following synopsis is taken from
MySoju.com, where you can find the links to watch the film with subtitles.

They soon find theirselves living with each other under the same roof because of an even bigger coincidence. Even though they share the same name and age, they differ in just about everything else. Even so, through hard experiences in love and life, a strong friendship is born between them, as both Nanas grow through their hardships and struggle to win the odds.
