I thought this would end up having a twist like the MC having been a dog and the whole world was just backwards because the witch was keeping it that way. It would've explained why the MC licked Mashiro's feet when they first met, since he may have actually been a dog in that scene.
Anyway the manga was a bit frustrating to read with how dumb the MC was acting most of the time to conveniently steer the plot away from progressing.
Also, I think this would've been a lot better if the author embraced the foot fetish aspect of the story a lot more since that really was the main selling point here setting it apart from other manga. I'm pretty sure there's an untapped market for a proper foot fetish focused manga.
