this is changed from the web novel, which to be fair, has alot of things different now that i went to read it, it also seems to have ended abruptly at vol 2 which makes me think the LN, which the manga is likely based on, has alot of differences to the web novel, which as far as i know hasn't been translated, so it's possible that like konosuba, this might be taking a different path than the original web novel, though that doesn't mean this is going to turn into a romance since it just "hints" at it being possible in the future.
