@Darklight99 Pretty much how I feel with a lot of them, though I think some are pretty good. But normally this is meant to take liberties with stuff and some scenarios are very much hit or miss.
The Shirogane x Hayasaka pairing though, that could have worked in the main series if introduced earlier enough, though by the time you started getting more moments between the two there had been far far too much with Kaguya so it would have been a mad move in general to switch heroines. Here, well it's completely separate so it can explore the pairing freely without worrying about the original story.
