Last Letter

Yuri (Matsu Takako) goes to the high school reunion of her older sister Misaki who recently passed away. She intended to inform the others of her sister's death, but instead gets mistaken for Misaki and just goes along with it. There, Yuri encounters her adolescent crush Koshiro (Fukuyama Masahiro), who is now a struggling novelist. Koshiro expresses that still likes her – her being Misaki. After the meeting, the two begin to write to each other, with Yuri continuing to pose as her late sister. To keep the letters a secret from her husband, she doesn't provide her real address. However, one of Koshiro's letters ends up being received by Misaki's grieving teenaged daughter Ayumi (Hirose Suzu), who gradually uncovers the memories of her mother's past.
