I'm a bit confused as to some of the details. What exactly was the purpose of any of the other girls' besides solving their problems and making Riki stronger. Also, will any of the changes (fixes) he has made carry over to the real world? For instance, will things still be resolved between Haruka and Kanata? Also, in regards to Kurugaya. Her wanting him to remember her in the real world? Wouldn't he already know her because technically all of them met previous to any of the events in the first 6 routes? I feel like I should add that I haven't completed Refrain yet. I found a recommended play order, and got so confused about what was happening in Kurugaya's route I ended up on a forum where I sort of found out about the whole bus accident and fake world.
