>>5650003Basically what
>>5650009 says. Just have them play the role of deuteragonist or something and it'll work out naturally.
>>5650018>worstI actually quite enjoyed Fate/Paradox Reincarnator throughout its run, but that was mostly because I only briefly skimmed the discussions between updates and completely skipped reading them if I ever got the feeling it was about to head into mind-numbing territory. That saved me a lot of braincells.
Setting that aside, a big part of what tanked it was the massive character bloat and ensuing war between the playerbase for who should get more screentime. It was a bit tough to really get invested in any of the characters when it seemed every other update saw a new girl to romance and solve problems for. It's definitely up there among the worst-case scenarios; most stories don't usually get that far before imploding, so it's quite remarkable to see how long the QM managed to endure the constant sniping. 40+ threads is an impressive feat.
>bestHard to say, really, since admittedly most of the Quests I read are off-site. Relatively recent examples that come to mind are Trust A Goblin (an artquest), Gaul Quest, etc. They set up the female counterpart early and establish a strong personality and goal, though I'm not sure if I'd call the heroine in Gaul Quest a deuteragonist. Those were all romantic interests, though, so I guess they don't meet the initial question's criteria.
In that case... I don't really know how to feel about saying this, considering it's my own work, but Necromancer of Eden Academy somehow ended up popular and the central character dynamic revolved around the master-minion sibling duo. I am *fairly* certain my players there weren't too interested in romancing the sister; they didn't really give off that air, though my perspective might be unfairly biased. There's also only one thread to go off of, so maybe it's just an issue of not enough development/sample size.
Attendant Quest also had a dual-protagonists setup, and I got the feeling that there was more of a fatherly attitude towards the FemMC there than a romantic one.
