if we take for granted that hayumi is just town for governour thing, yoho is just town for watcher/ninja interaction, we're left with 6 people (i mean 5 for me)
i'd remove pero tbh, for reasons mentioned already
so flower/orca/michelle/ytw
michelle/ytw then? since in this scenario we're assuming hayumi is town and she doesn't think flower-orca makes sense, even if flower is scum, she'd be scum with one or two or michelle and ytw
so hitting one of ytw and michelle makes the most sense, right?
i'd start with michelle since yoho believes ytw is town and michelle could be gf
