Feel free to ignore this post.
I'm not sure what to think of this. It was really good, but ridiculous in places. Some parts made me feel very uncomfortable. I didn't like how Kaede died. I didn't like how she and Nyuu were reborn at the end. Even if it was meant symbolically, it was awkward for me. I liked how some things toward the end were very well put together. I liked how she sang, giving us an answer to the name of the series. I liked how she sacrificed her life to save Kouta. Most of all, I found it unbearably depressing; a girl who was told constantly that there was no place for her to live in her world, who wanted to live happily with someone who showed her light amidst misery, but wasn't allowed to. The note at the end showed me that...her brief visit to being a normal girl, shown through the line "Ah, I want to wear a wedding ring...", essentially the momentary desire she had of a happy future, completely crushed. It was devastatingly sad to watch through Kouta's eyes as he digs up this memento of their past. I don't even know how to describe it in language.
I can't say that I didn't like it, but I almost can't say that I did like it. It was stupid in places, but amazing in others. It didn't make me cry the way the anime did, it just made me feel depressed. I really don't know. It was very good.
Sorry for going on about this randomly...I just felt like I needed to write about it somewhere. I gave it an 8/10 overall, but that doesn't really mean anything. I can't think of a way to summarize how I feel about it. I do know that, as a writer and artist, this has been a heavy inspiration and learning experience for me, and the series of novels I'm working on (if I ever get them done) will show clear influence from this story. So yes, I guess I can say that I really, really liked it.
