Despite being a very light read, this manga truly had everything: enjoyable characters, interesting plot, cute romance that wasn't too over the top either, and a great protagonist. At first, seeing the number of chapters, i thought it would definitely feel rushed towards the end, however I think since it was meant to be a nice little short manga, the development and conclusion felt nicely paced and the bit of action packed there felt refreshing too! Another good point was that there weren't many loose ends, except for just one that I'll talk about either, and the plot holes weren't too in your face so unlessyou're being specially nitpicky they don't become too much of a problem, and in my opinion they can even be covered with your own rational thinking based on the world building, like Eco's magic knowledge, how couples work, etc.
The only and main loose end by the finale is related to Eco and the reasons she's able to use magic. Although some may think it's central to the plot, I think the mangaka was mainly indecisive about what the main plot point was gonna be, since Eco didn't have as much interest as anyone else in finding out the source of her magic as much as just being able to use it freely and without being judged. Though it's true that point in particular could have been used if the story were to have gone on for longer, i think the two volumes and story resolved were plenty and it was a truly enjoyable read.
