Cinderella Phenomenon isn't bad, she's pretty bossy in a few routes though overall it's more equal. 7kpp, though still in development has Emmett, and while there's no much bossing about he is easily flustered. It's been a while since I played Sweet Fuse, but I can only think of one route where she was really in the dominant role. In the others it was more of a mix, though she's definitely a feisty one. I keep coming up with more (all indies, I'm happy to make a list if you're interested), but usually they're in the "close but not quite" categorey.
I wholeheartedly agree with you about wanting to see the guys flustered rather than the MC. Both can be fun, but we're already drowning in flustered MCs. I'm glad you decided to go with something different.
