"I've watched and enjoyed all of Key’s previous anime adaptations... but to a large extent, if you’ve seen one, you’ve seen them all. One guy and his harem of mysterious girls, each with their own character arc. And since this one isn’t being animated by KyoAni, that’s one less reason to watch - the trailer didn’t look as nice as Kanon, and that was 10 years ago! While I’d probably really enjoy this, I think it can wait until later. "
The VN is ****ing incredible, don't bother with the anime. Considering it's already been confirmed to have 13 episodes, it's unlikely that it'll be anywhere near as good
