The last page's remark is a slip on my part, I just fixed it. I also added a T/N on the affected page, to explain why I wrote it that way. It was on purpose. First, mangaka might have misunderstood the meaning of treating on Halloween, as it's Sensei who's supposedly meant to trick Nako, not the opposite, plus Nako spoke in broken English, so I tried to mesh all this into French to be consistent.
