One of the best reincarnation/reborn manhwas in existence. Characters actually feel realistic. The villains are still pretty one faced with the generic "We want more money" or "we're nobles so we're better than you" but as the story progresses, that should clean itself up.
The MC is reborn in her second life and this time she wants to make everything right. A similar premise to a lot of Villaness manhwas but this MC didn't actually do anything wrong the first time, besides being a bit to unambitious and passive.
The MC is only 5 or 6, but they have a mental age of around 20 or so. This manhwa does well with regulating that, making the character use prior information and critical thinking to utilize situations while also portraying themselves as an actual kid. A lot of other stories will just have the reincarnated/reborn child become Shakespeare at age 4 and then branch into astrophysicism and sage magic at age 6 and the MC will directly show other characters their advantages/abilities. This MC does well in balancing being extremely able in her past life and having all this information and skill vs. getting reborn and being a kid again.
The romance is between the MC and the second prince, based on the cover art. My biggest idea is that she'll save him from the palace, they'll be friends, and when they get older, he'll start liking the MC.
The MC will most likely utilize the Lombardy wealth and connections to build the ultimate medieval conglomerate ever seen. Hopefully at that point, the author can figure out a way to keep conflict going or just end the story. I don't really wanna see a lot of plot holes, convolutions, or filler. If you're out of ideas, just make a good ending and say goodbye
