I recommend this purely cuz of the main character. She was brilliant, she planned everything out so well, she was smart, kept learning, developing herself in many ways. She didn't rely on others, she built her own power and knew how to use it. I loved her so much. The guy she is going to fall in love with was also great, although not as much as her. Visually beautiful, side characters were ok, could use more development of their past. The plot was nice and its development as well. The main antagonist was really stupid and annoying, I know we should hate her, butgive her a chance to at least be any threat and give us some emotions when the main character wins vs her...
It's not very original, as other isekai stories start the same way and she does end up with one of the main characters, but I still recommend it.
