tl;dr: A manga adaptation that has some weaknesses, but is overall a very good blend of romance and economics.

This manga is an adaptation of a light novel that was also adapted into a pretty popular anime. It is primarily centered around two core aspects. The first core aspect is the story of Holo and Lawrence, their relationship and their growth. It's an incredibly slow burn romance. A lot of their interactions stem from them both constantly teasing each other, with Holo generally being the one to start things off, but they're both also very cool headed and able to respond well to such teasing, and thus it's like something of a game between the two. There's some very subtle shifting in this which shows their relationship progress, but it's really subtle and thus overall, the relationship does feel quite slow. There are moments in the story that break from this and have more intense and honest moments, but for the relationship buildup things are very rarely explicit.

They do eventually properly become honest with each other and their relationship fully clicks, but that felt like it was a bit weak in that the transition wasn't handled that intensely or with enough impact, even though their relationship did clearly change afterwards. Them properly in a relationship was handled quite well too, where they properly consider together various things like what's most important to them and what they want to do and how that's changed from how things were before. Though it felt like there was a lot that was touched upon but not discussed in that much depth, such as Holo's immortality. This aspect also ended incredibly well with a pretty lengthy epilogue dedicated entirely just to it that finished off the manga perfectly, though I believe the novels continued past this and are still continuing.

The second core aspect is the various economic schemes and such that Lawrence gets involved with. I'm certainly not an economist, and know pretty much nothing about medieval economics, but what was shown and described felt pretty believable and consistent. The schemes themselves felt pretty well thought out and told pretty well in that they had good pacing with twists that worked well. Still, it did feel like it wasn't explaining things in that much depth. This was fine for most of the schemes, because they weren't too complicated, but the last couple were on another level and felt like they definitely could have used more explaining because I had to think about parts of them quite a bit, rereading portions in the process, in order to understand them and certain parts still don't completely make sense to me.

These schemes are episodic, in that very little from earlier ones affect later ones. I should note thought, that it is very clear that parts were definitely skipped, and that felt a bit jarring at times. All but the last episode also have very little to do with Lawrence or Holo personally, but rather are them simply being involved in situations where they may make or lose a lot of money. There are pretty solid stories behind each of these schemes, and the side characters that are involved with them are pretty decently fleshed out as side characters, though only to the level of side characters. Still, their relationship with Lawrence and Holo, and just as importantly their effect on the relationship between Lawrence and Holo, was substantial and well worth reading. Each of these episodes is self contained and has a pretty solid ending in their own right, but the ending of the manga overall does a good job of bringing them all together in that it doesn't involve any sort of scheme of it's own but it does bring everyone from all the episodes together which is a great way to end things as it makes the impactful ending focused on Holo and Lawrence even more impactful.

The art was decent, in that it could definitely be good at times, and consistently was with covers and full page illustrations as well as in both the beginning the end, but for the most part it didn't feel like it was trying all that hard and though there were panels that stood out, for the most part it looked kind of dull.
