The Sorrow That Cannot Shed Tears (The Original Novel of the Film Starring He Landou and Greg Hsu)

Reading this book seems to be splitting up memories, jumping frequently between the past and the present, which is a bit tiring. There is also a setting that I don't like. Because of Alzheimer's disease, the heroine's memory goes back to the past. She was a young girl and regarded her son as her boyfriend, which was unbearable. Also, when I went to find my boyfriend with my uncle, there was an earthquake. My boyfriend's legs were pinned down by a big rock, and his flesh and blood were mutilated. At that time, I was still thinking, it's over, the male protagonist must be disabled and lame, because the male protagonist must be unwilling to reconcile, for fear of dragging down the female protagonist. Who knows, the female protagonist suddenly regained her memory, and then there was no earthquake or big rocks. This is the world imagined by the female protagonist, or is it because I didn't read the book carefully?
