Is there a name for dynamic that is not friendship nor romance nor enemies nor anything else really, but just something completely unique?

Like Amanda and Connor

I don't ship them, but there is some romantic component to their dynamic although it's not enough to classify them this way. They're not exactly enemies or colleges too. I don't want them together or anything, but I just want their relationships explored in their complexity. What would such type of relationships be called? If I wanted to read something like that, what would be the tag?
