★Afterword★ Thank you very much for picking up this doujinshi by ALISON AIRLINES. As announced on my Pixiv and social media, this is a draft version of the book. It is very difficult to find time to research space-related literature and write a doujinshi as a working adult, so I apologize if I don't live up to your expectations. I will post it on my Pixiv and other social media when it is completed, so I would be very happy if you could take a look when it's ready. The artist never posted it on their Pixiv
