>>1865463I always thought it was well worth my time to comb through those novels as they gave me a better perspective on the characters / story, and I wanted to know what is going to happen in the future. Besides, while I already liked the anime version of Kirino, going through those novels made me like her even more.
As for wincest... I actually prefer how it is handled here. Not as something that is jumped straight into, but as an undertone of the growing relationship between the siblings.
