For those who don't know, Aoi Bungaku is an adaptation of 6 classic Japanese novels, namely No Longer Human; Sakura no Mori no Mankai no Shita; Kokoro; Run, Melos!; The Spider's Thread, and Hell Screen.
Of these, I've watched all of them, but I've only read No Longer Human. I'm interested in reading the original novels, but only if there are significant differences in terms of plot. Are there any major omissions or changes in the anime that would merit reading the novels?
The ending of No Longer Human has at least one such difference:
In the ending of the anime Yozo commits suicide. In the end of the book he gets sent to an asylum and then released to an isolated place.
Do the other works have similar differences (preferably with as few spoilers as possible, though some spoilers are inevitable)?
