Five years ago, I lost all memory of myself. Alone, I went to the distant United States.
Five years later, a silver whistle reminded me of certain memories from the past. So, I returned to that familiar town again. Aunt Cai, who has been in contact with me for six years, has always been unwilling to tell me about her past memory loss.
What is she hiding? What is the reason for my anxiety? Everything, I just want to find the answer, but what is the answer? A complete answer? Or is it a continuation of a nightmare?
