So, after catching up with reading your "bible", I decided to read this. (Moving onto the next story after I write this comment, of course.) One thing is for sure: I'm crying with everyone else who cried because of this story!
I wasn't sure how the story could really be continued when I finished up the last part of this story with Miki in the Aya-less world, and I figured this would be a continuation where Miki could finally heal her wound, but with this, I see that even with stretching it out, it's still a very emotional and complicated situation for Miki to face. The two of them were meant for one another. They were matching puzzle pieces that only connected to each other and nothing else. (I'm not saying they didn't have anyone else important to them, such as friends and family, but I think/hope you get my point.) JFC's explaination is all in all breathtakingly true. It's hard to get over something so trivial. Something that brings so much impact amongst oneself such as death or seperation.
Shibata actually annoyed me this time, but I think she only had Miki's best interests in mind. Well, not completely. Sending her off probably wasn't the best idea, but I do think it was good that people told Miki she was pushing them away as they were only trying to help her. (Originally, I thought Miki had called up Yossi, because they seem close. Then, when the romodel talk came in, I began to think, "Ah, it's Koharu!" Let's just say I was really defeated in the end. xD) Anyway, perhaps Shibata thought going away would make her change interests, find someone new, or discover something in herself. But, I don't think sending her away was the way to tell her. Miki's conversation with Michishige was perfect. I think Miki really needed that. She does still need friends.
Also, the encounter with the priest was very . . . spiritually lifting, though I have no interests in any kind of religion whatsoever. I find it strange/neat how people can find inner peace just from looking up to some higher being. People should really learn to look up to themself, I personally think. Still, it was an important encounter for Miki because the two of them could relate. She wasn't feeling peace because she was in a church. She was feeling peace because someone else understood her pain, but somehow managed to get over it. They were the same, but their outcomes and professions were different.
Okay, so I'll stop typing this boring stuff and let one more comment sum up my feelings: I loved it, just like everything else you write.
