What's the difference between this and the alternate story?

At the time of writing this, there are only 3 chapters out.

Because the series so far are the same I'm gonna use the same review,

In this one, the art style is more moe. Also, the MC's backstory is expanded on in this version of the manga than the other. You get to see her grow up and invent her frist two inventions. This version also follows the LN more closely than the other.

The premise of the manga is nothing new in the isekai genre. Staring the story off by having the MC's engagement fall though is commonplace for isekai's with female leads. However, I do like the fact that the MC isn't a princess or the daughter of some noble. Yes, she is the daughter of a famous inventor. However, she has built up her reputation through her own capabilities and hard work.

The MC is a strong independent woman who don't need no man. Which is a nice change. Most female-driven isekais have the success of the MC driven around a relationship with a male counterpart. This is even true for most strong-willed and powerful heroines that I read. So it is really nice to see that the MC's success isn't driven by the MC's relationship with the pretty boy Knight.

From looking at what people are saying about the LN, this should grow into a nice series. Looking forward to how it plays out.
