Lots of bad grammar, but it's okay, you will improve.
Sad, the best girl doesn't have a route. Does all 5 girls get their routes later?
English isn't my main language, but I try REALLY hard to correct bad grammar. I used to really suck with double past tense or double negatives. People pointing out these things don't bother, quite the contrary, it helps me to improve and correct the script, if possible.
Also, yes, all 5 girls will have their own route eventually. AND all side characters will have a bigger role in the last 6th route: the harem route, that although non-canonical, will be at the very least very fun.
