Katarina is on the asexual and/or aromantic spectrum
- Even ignoring her obliviousness, Katarina never expresses any real desire to pursue any of her friends in a romantic or sexual way.
- She is described as "immune" to the charms of her various suitors, like Nicol's smile, while others are usually affected.
- Her fantasies about growing old don't involve a significant other or anything, just a cat on her lap.
- Despite acknowledging and appreciating the attractiveness of her friends, the closest she gets to showing actual desire is with wanting to touch Sophia's hair, being in awe of Nicol's smile at first, and swooning over Maria, none of which bar her from being ace or aro or somewhere on either spectrum.
