Sidenote: To be clear, this story is told from the perspective of the narrator and focuses on one characters pov. To avoid confusion, I'll warn you ahead of time that the narrator is telling the story from main characters point of view but from two different time periods(Past and present). So understand that when reading the story you'll find that story abruptly changes between the present the character lives in and the memories she relives. So hopefully that helps you follow the story better.
