I didn't even notice until I saw your comment. Ik sometimes artists do that they'll accidentally add or forget a finger when drawing but it actually happened quite a couple times in the chapter. I hope it's not and it's just weird positions or they truly just was having some mess ups. (・–・;)ゞ
Lots of secondary couples with no complete lore and a rushed ending, WTF. The story has potential, but it really left me a little disappointed.
