I also really love the main character, Echinacea. Most of the times when characters go back into the past, they use their knowledge of the future for self-gain, to get richer, etc. which is fine (I'd totally do the same), but she uses it purely to save people, to the point she's willing to risk her own life, multiple times. She's so strong and isn't afraid to put shitheads in their place, but she's also extremely hard on herself because of what happened in the first timeline. Her self-loathing is intense, and the author described it so detailedly that it's very very sad to read... like you can understand why she feels the way she does, so it's not annoying like when other characters victimize themselves. I cannot think of two main characters who are kinder to each other but unkindest to their own selves, and I think that polarity is what makes me love their love story so much more.
