This manga is overall a pretty standard but solid introduction to a larger story. It is standard in the sense that it feels like a pretty generic romcom. There are some interesting concepts, such as a hero that's super stingy, and a heroine that's trying to kill the hero, but for a good reason, that add some flair to the humor that keeps it from getting boring. Still, it does feel a bit slow at times, because while I'm not opposed to side episodes that are used just to give more time to the characters and their relationship without pushing the plot forward in any meaningful way, these sideepisodes weren't particularly interesting, just sort of middling in terms of quality and also somewhat cliché. As it approaches the end, it does set up some interesting concepts, such as some new twists on the relationship between the hero and heroine and setting up a new direction for the plot to take, but as this is just a short adaptation of a light novel series, it ends at the point. All things considered, this is a pretty good break point, though in the end it still feels like it ended too quickly, but I suppose that's inevitable considering what it was meant to do. The art was okay.

tl;dr: A manga that is a slow but solid start to a larger story not to be adapted.
