After listening to the tape that Tang sent, she feels as if the kindness of nature is calling her, and travels to Taitung to find the mysterious man who sends her the tape.
Just coming out of the jail, depressed and close-hearted, Ah Yu met two men with different characters from each other.

With a wounded soul, she went back to the cottage owned by Sister An, a friend from jail.
