A brief synopsis of the movie "Tokyo Boys" Thank you

Fujiki Minato (played by Maki Horikita) lost her parents when she was young and lives with her grandmother (played by Reiko Kusamura). Her pen pal "Ye" is the only person she can open her heart to and talk to her. No matter whether she is sad or happy, Minato will always write down her feelings on stationery, put them into the red mailbox on the hill, and share them with Ye. However, Minato has never seen Night, and only knows that he is a boy of his own age.

Minato met young Karasawa Hide (played by Takuya Ishida) while working in a convenience store. She wrote a letter telling Ye that she had fallen in love with Xiu.

Xiu also has a crush on Minato. They went out on a date on their day off and had a very good conversation. Xiu took out his camera and told Minato that his father (Mitsuru Hirata) was a famous doctor and asked him to apply for medical school to inherit the family business, but he did not want to give up his dream of becoming a photographer. Minato was about to speak to encourage him, but suddenly lost consciousness and passed out. After waking up, Xiu's attitude changed drastically, and she finally broke up unilaterally. Minato has suffered from temporary amnesia from time to time. She doesn't understand what happened and what to do to save Xiu. She can only vent her sadness in a letter to Ye. However, she didn't know that the jealous Ye was actually the murderer who destroyed her love.

Minato decided to meet Ye. That night, she searched for the address, only to find that it was an abandoned school. Suddenly, Minato saw himself in the mirror, and felt a strange feeling in his heart.

It turns out that Ye is Minato, and she has been communicating with herself in another personality...
