Atsushi is pleased to hear that her mother's friend, Airi, who followed her husband's overseas assignment, will return to Japan. When I met her again after a long time, she became even more beautiful. As she helps her move, the distance between the two gets closer and closer, and her past feelings overlap with the present, and before she knows it, they have a relationship. The two of them secretly meet each other not only as childhood friends, but also deepen their bonds of pleasure. However, Airi decided to cut off her relationship with Atsushi, saying that she could not continue to do this forever.
