You got everything ok until that part so keep it up! You have a long journey ahead of you so good luck.
Bethley and Yuzuki are the easiest routes to read probably (specially bethley's)
Hinata's route is probably the hardest but funniest (I will create a blog one of these days to talk about her route and momiji)
The choices to pick a girl are really easy to spot (only 2 of them matter, the rest are meaningless)
