This is a completed first part in what, as I understand, is intended to be a series. This is an excellent VN with enough choices to make you feel involved, great sex scenes, a likeable protagonist, and a genuinely interesting story.
The only reason I think it feels short is because I was so caught up in it. It is a complete story, the author has said, and it is satisfying for a first part.
Worst part about this VN is the fact that we have to wait for the next part, haha! In all seriousness though, I wish Mortze and their team all the best, and look forward to their continued work on this series, and anything else they may dabble in.
