Was commissioned by agitch (https://www.pixiv.net/en/users/29019908).
Regarding the title, the first is the name chosen by the artist (as you can also read on the cover) and the other is the title under which the commissioner uploaded it. I honestly don't like the cover though. To me it implies that there is more going on. Maybe that's why the commissioner uploaded it without a cover?
Nevertheless, do you like what you see? Then leave the artist some support, here are all his most important links.
