As a guy who has read manga, novels, and watched anime, this is honestly pretty bad. I'm not saying it's bad, but it's pretty bland. The author created a pretty good start when MC came from another world reincarnated into the villain and changed everything. The butterfly effect through the small actions she did really impacted the plot and took it in a different direction. However, it has a serious problem that many novels have. A great start, but as it goes on, it gets worse and worse and eventually ends quickly or is abandoned. It's like a bowl of soup where everything is mashed and mixed together. The first bite will be very delicious because of its variety, but later on it will become more bland and tasteless. There is no highlight, no climax, we finish the bowl of soup without any flavor remaining, like a roller coaster. That's about the plot, the character development is also poor, the MC is like a robot that only works when given orders, the supporting character is brainless
