Y, a young man on a remote island, had thrown away his phone, unable to trust people. The only one he connected with was Yuko, a woman from a net cafe. He lent her 3,000 yen, and they shared childhood memories of a cosmos field. One day, a letter and the 3,000 yen arrive; visiting the address inside, Y finds a vast field of cosmos in bloom. He learns to trust again.
