How does the author use foreshadowing in Shizuko's Daughter?

Most of the chapters in this book begin with the present tense, with the narrator discussing what is happening at that particular moment. It is through the present event that the narrator then remembers something from the past. In this way, the author is able to fill in the details that lead up to the present moment and foreshadow future events. For instance, since Yuki's mother dies in the first chapter, the narrator, through flashback scenes, relates to the reader the possible reasons for her depression and subsequent suicide. Allowing the audience to view past events helps readers understand Yuki's emotional outbursts, facilitating empathy for the protagonist.
