Japanese movie (言叶之庭)

A few days before I watch several short vedio about (言叶之庭) which is directed by 新海城. I am attracted by the love story between two ages.

He is a student and meet her unexpectedly during rain day. they meet again and again in rainy days so they began to talk with each other. He shared all his thoughts his life to her, but she seemed mysterious and kept hers.

one day he came to her deployment and told her he loved her. However she told him she will move away to other place and never meet again.

he is angry and ran out which let she understood her real mind. I don't know the ending so I prepare to watch complete one on vacation.
