I see ghost hands or whatever they are appearing a lot in Asian countries as far as ghost-related stuff are concerned, but are they just as common in the West? I don't know.
The ending was kinda spooky. I bet Yabe can't wait for them to graduate. The way he was holding Okazaki on the ground was super lewd. I'd love to feel her sides like that while having her body lay on top of me.
See... regular chapter that progresses. Gal still stays within her role and tries to force progress on Yabe. Yabe being the dumbass MC (good guy) that he is still gets into trouble because of it. The harem continues to blossom in the country side.
