Kate is a character in the novel You Exist Too Much by Zaina Arafat. Just like the unnamed narrator of the novel, Kate is bi.
The narrator says that she and Kate “had been secretly sleeping together for almost a month” when the narrator notices a bruise on Kate’s upper thigh. She asks her what it is, and Kate says: “Oh. Blake […] He does that when I’m on top of him.” The narrator feels jealous about Kate having a boyfriend.
Kate is a student who is “taking extra classes” at university.
Kate is described as “a ‘best-looking’ senior-superlatived, field-hockey-captained, Camel Light-smoking […] straight woman”, but the fact that she has a relationship with the unnamed narrator — a woman — indicates that she is not straight but bi.
They do not acknowledge their relationship for what it is, however; the narrator notes that, during daytime, Kate and herself “had never spoken about [their] nights”.
When Kate kisses the narrator in public for the first time, the narrator says: “I don’t want to ruin our friendship” but Kate laughs and says, “Don’t worry. We’re just, you know, ‘experimenting’” and they later argue.
Eventually, Kate says to the narrator: “I want to marry you” and later on, Blake ends his relationship with Kate. However, the narrator notes that, two years into her relationship with Kate, she begins “to drift” and finally, their relationship ends when Kate moves to Florence.
