Hello, I just read 10 kago ni menhera ni naru gyaru[m], and I just remembered reading a serie similar to this, which is about a girl becoming more in love with a man in x days, and after that it transitions into that same girl becoming more of a yandere instead. I want to know the name of the series.
  What is the name to call this type of story where the story progresses in days and recommendations for series that progress in this style?
