Not really

Spoiler for Her reason I think is:

She blames Kyousuke for having been manipulated by Manami into becoming a mere shadow of his former self. I assume she hates Manami for existing but nobody has to forget Kyousuke is partially guilty for falling for her scheme as well, if we can call it like that. Of course, going by what people have spoiled here, he was very depressed at the time so it was easy to "mind control" him but.
