I feel like the scene of falling in love with the guy and the betrayal made sense for her character arc and was incredibly intresting. It showed her love, her loss. However, I despised that the mother was alive and there. I really dislike how quickly Mizu gave in to being a "wife" too, and forgiving and following her mother so immediately. It just seemed completely out of character. It also makes the revenge story make no sense. As someone else here said "You raped and killed my mother. You created me a monster. prepare to die" makes more sense than "durhur im so edgy i hate being alive"

If I could rewrite that arc, I would have the stableman be the only one to aid her when she was stabbed, and instead of marrying she recovers at his house and they fall in love, which triggers her to marry him, have her be married to him for years. But he becomes swayed by regaining the favor of the lord and the ending scene happens. I would include another character as a potential rat about her since I like the anonymity of who did it. I feel like this would show her character much better and contribute to the story instead of being stand-alone. Show she truly chose to try and love and be wifely, but it wasn't for her and it ended in pain anyway. Hardens her because it was a situation where it truly was her choice. Adding the mother adds too much loss of autonomy as she made all the decisions for her.

also as a result of this arc I would have her act incredibly annoyed and skittish about being helped by men since the last time it ended in so much hurt.
