The following is an excerpt from tvtropes that I feel describes Ruby, from Jaune's point of view. I've removed links because I don't want to get anybody stuck in there:

The Not-Love Interest is the phenomenon in which the character who fulfills a typical "Love Interest" role doesn't actually have a romantic relationship with The Hero. This trope often represents a Subversion of one or more Love Interest tropes, or tropes that normally lead to a character becoming a Love Interest, such as Rescue Romance.

This trope points out that certain roles and dynamics are frequently shared between the hero(ine) and the Love Interest, or that characters in these dynamics frequently evolve into a romantic pair. This is so common that when that is Averted or Subverted, viewers are surprised by a non-romanticized relationship. The Hero may have an actual love interest, but they will usually be less significant than this character.
