One of the issues I had with KoS was that it just had too many side girls, so I ended up skipping content from quite a few of them, either because I didn't find them as hot as Mary or because their NTR was nonexistent or not as relevant to the main story.
That issue isn't as prominent here at least, given the size of the cast, but still, I find myself not finding Hanako's scenes as exciting because, well... she isn't in a relationship with Satoshi to begin with, so the NTR doesn't quite does it for me.
Don't get me wrong though, this is still my favorite game from the developer at the moment. Just hope i feel different in future updates regarding that aspect of course.
