Yeah the old man is cool (funny old playboy), however after leaving him he was not even once mentioned in the story and he didn't have much of a relevancy to the story IMO (for example they could have implemented that Tonoya mentions him in one of his scenes before the graduation concert, because he was clearly hyped about him on the phone).
On the other hand meeting with Kashiwara's Uncle was really crucial in Kashie's route.
Well, Midori only really made me RAGE at the end, but her story was meh. Not to mention that until she's 21 year old, she needs to have a guardian until that, so I really really doubt she could just enroll in such a community so simply like that. But I was particularly pissed when she furiously intervenes with someone else's really delicate family circumstances despite only knowing her for a short time. I bet not even Chie would have appreciated that if she finds out. (If I recall correctly she's not aware of it.)
Well yeah the character sprite indeed seems like she's after giving birth, however I had the impression reading the conversation that she was still pregnant. Well I may have been wrong about that though.
At the very least Kashi's route was better IMO, because it had less drama, and I felt as if it was less "forced" in a sense therefore I could sympathize with her a bit better. The part with breaking the guitar for example or arguing with the Grandfather was really touching. And Kashi's ending wasn't so abruptly ended like Chie's.
Don't worry it's not my first VN
(according to my VNDB list I'm closing on 100 soon O_O ), so I'm saving at every choice
