This anime was really good to watch but can be emotional.
The story is about a group of friends that get letters from the future. They then use these letters to help a friend not commit suicide.
Nano, Hirota, Saku, Azusa, Takako, and Kakeru are the main characters. Nano and her friends save Kakeru from committing suicide. I really liked this group of characters and think they seem like a good group of friends.
I liked the openings and endings to this show. I really liked the animation as well.
I loved this show and give it a 9 out of 10.
