I made some tweaks to the draft. I cut out the second paragraph because it was pretty reliant on the old friendship-specific definition, and elsewhere in the description, I changed references to friendships to references to relationships in general. One type of relationship I added to the list of types of relationships was business partnerships, since business partners have a relationship that doesn't necessarily involve being friends, though I can't think of anything else to add/change at the moment. Maybe someone else can pitch in.

I removed Strictly Professional Relationship as a subtrope, since according to its description, it involves feelings of attraction that are not acted upon.

I kind of figured we'd need to adjust the subtrope list, but didn't look into it around when I trimmed the description.

I'm just going to close this because I figured if further clarifications are needed, it can go through the Trope Description Improvement Drive, because I think the current description at least accurately fits the revised definition regardless of whether the wording needs any minor tweaks.
