Perhaps instead of a Harem%, a "sleeping around" category would be a suitable replacement. I believe that despite only being allowed to have 1 relationship at a time, you can still break it off to lock it off and be able to start a new relationship. Working title: Heartbreaker%, where you complete all romance quests and have to break up with everyone.

I'm VERY new to speed running, and I figured to start out with the first game I ever truly loved. But from my limited knowledge of speed runs, I think it's a big missed opportunity for a run to complete any romance quest as fast as possible. Similar concept is the GetLaid% in Breath of The Wild, or the Marriage category in Skyrim. I'm thinking of calling it Bard% I've never tried getting multiple romance quests completed in a single save file, but if it's possible then maybe an all romance quests run called Harem% or something along those lines might be a neat additional category
