@ninehell, you probably won't end up seeing this but its pretty clear kaoru's princely shakespearean shtick is just that, shtick. a facade if you will. since chisato is childhood friends with her she knows what the real kaoru (an absolute bottom) is like underneath it all, and it seems like kaoru's facade annoys her for that reason and it makes her mad that kaoru puts it up even around her.
Miku: Um, Hibiki... There was something I've always wanted to tell you. Hibiki: Yeah, me too. Miku taken aback Hibiki: I hope what I want to tell you is the same thing you want to tell me. Fade out Title Fade in Miku: So we both are in love with your father, Hibiki!
(Otherwise why did he even have scenes in this season? Plus Hibiki was only able to win with his help. It was so jarring.)
^ The only Harvest Moon game I remember that has a "proper" yuri route (4 to be exact) is the Japanese version of Harvest Moon Cute. Sadly, they took that out of the English version. Their heart events are still viewable but they won't accept the blue feather (I still don't get why Marvelous had to take that part out cries).
