The film is a remake of the South Korean hit and will be shuttling between the present era and the 90s. Shinohara plays Nami, a full-time housewife who wants to reunite her buddies from the group "SUNNY" when they were in an all-girls senior high school after knowing that one of her best friends Serika (Itaya) is down with terminal cancer. However, it has been 22 years since they last gathered so it is an uphill task trying to locate everyone. Koike plays Yuko who is the wife of a rich man while Tomosaka plays Shin who works in the sex trade and has financial difficulties. Last but not least, Watanabe will be playing Ume, the owner of a real estate business. Another key figure in their group Nana will be played by another actress which will be announced at a later date.
Hirose plays the senior high school version of Naomi while Ikeda plays Nana who was the cool beauty in their group. Yamamoto will play Serika who was the leader of Sunny and Noda, Tanabe and Tomita will play Yuko, Shin and Ume respectively. In order to look convincing as senior high school girls during the 90s, the 6 actresses had to dye their eyes and put on make-up to make their eyebrows thinner and their complexion sport a brown tinge.
