Hello everyone,
First off, I would like to thank you all who picked up this series. Thanks a lot for showing your interest in the series. As you might have guessed already, this is a novella, not a novel, so it will be of a much shorter length than average novels or Japanese light novels in particular. You need not know anything about photography or astronomy at all to start reading this story. The MC starts much worse. I will also add illustrations aiding your understanding. This might be enough, paired with the explanations.
Well, for the first author's note, this should be enough. I would like to once again appreciate your interest in the series and would love to hear what you think of it in the comments.
That's all.
