There was a movie in which a girl named Nami was teased by her classmates because she couldn't speak the local accent well. Then six girls made friends with him.

The film tells the humorous story of middle-aged women in a small group of middle school sisters Sunny who once called themselves "Seven Princesses", reunited after 25 years, looking for youthful memories.

In the film, the members of "Sunny" of Seven Princesses Middle School will be played by Shen Enjing (as Nami), Jiang Sula (as Chunhua), Jin Minying (as Rose), Jin-ju Park (as Zhenxi), Bo-ra Nan (as Jinyu), Jin Baomei (as Fuxi), Min Hyo-rin (as Xiuzhi) and other new generation actresses. Public opinion is very interested in whether there can be a second Park Boying among the actors.

Sunny is a group of seven princesses reunited after a lapse of 25 years, and its members will include Mesozoic powerful actors such as Liu Haozhen (Nami), Chen Xiqing (Chunhua), Gao Xiuxi (Rose), Hong Zhenxi (Zhenxi), Li Yanjiyong (Jinyu) and Jin (Fuxi). It is reported that the production team attaches great importance to the similarity between the two groups of actors in casting, and this lineup is also the result of thousands of choices. The biggest feature of the film is to tell the stories of the ancient and modern "Seven Princesses" alternately. [1] Transfer student Nami (played by Shen Enjing) has just transferred from a small town in Jeolla-do to a new school in Seoul. She speaks dialect because she is too nervous. On the first day of school, she was bullied by a group of classmates and got help from a group of girls: Chunhua, who is good at fighting (played by Jiang Sula), Rose, who is eager to cut her double eyelids (played by Jin Minying), Zhenxi, who is good at swearing (played by Jin-ju Park), Jinyu, a literary girl (played by Bo-ra Nan), Fuxi, who dreams of becoming a Miss Korea one day, and Xiuzhi, who is always proud. Nami soon became a member of this group of girls. They also changed the name of their team to "sunny". They vowed to be together forever. However, just as they were preparing for the school celebration performance, something happened, which led the girls to go their separate ways. .......

Twenty-five years later, Nami (played by Liu Haozhen) married a successful businessman and had a beautiful daughter. Her life looks perfect, but she always feels that something is missing from it. One day, when Nami was visiting his mother in the hospital, he accidentally met Chunhua (played by Chen Xiqing), and they were ecstatic after meeting. But Nami learned the fact that Chunhua is a cancer patient, and there are only two months left. Nami asked Chunhua what happened, and she could help. Chunhua made a request, hoping that Nami could find out other members of sunny.
