I wanted to update my opinion on the game because I've finished all the routes today.
Kyo's route was the best
by far. His character is not much better than the others but his route is not as crazy and one thing I liked is that times passes (MC mentioning that months have passed away for ex) so it doesn't look as rushed.
MC was as idiotic as ever but in this route she was more likeable.
But what really make me enjoy this route was Higarashi (sp?), Kyo's secretary. Most of his scenes were funny and I loved how he connected with Kyo.
The end is very open. It would make sense that there was a second route. Someone who knows japanese could tell me if it has already been released in the japanese game? Though I do not have much trust that they decide to make a second season in english.
So my recommendation is that if someone is starting this game and wants to enjoy the game to choose Kyo. I still believe that the route with more potential was Kairi's but the writing is a mess and the sexual abuse won't go well with most.
