Teachings in the Story

Read the words of your past self

The characters read letters their past selves addressed to the future, and gradually notice dreams and hopes they had forgotten. How the present self receives the wishes of the past is placed at the center of the story, and becomes an opportunity to choose the present again.

Notice your true feelings through the lives of others

The protagonist who delivers the letters also looks at his own true feelings as he touches the lives of the five recipients, and begins to think about a new step. Points of contact with others become an opportunity for self-understanding, portrayed in a flow toward a fresh start.

Deliver directly the letters that cannot be delivered

The Special Difficult-Delivery Response Office delivers directly to recipients letters that cannot be delivered for particular reasons. Through their mission of delivering five letters in two weeks, Hideo and Kaito meet people in various places, and the conditions of the mission are also given concretely.
