The problem stems from the entire concept of a 'Saintess'. They forcibly KIDNAP another woman from a different world and expect her to do everything for them. They expect her to fix their problems, heal them, do everything! They're expecting them to be like obedient subjects and follow orders...
She needs to pick a stance. Is this more than a story or not. If she really does treat these people as real human beings and more than characters, then stop going on and on about the 'heroine' or the 'plot'. My goodness it's getting annoying.
My god. If she really believed that things should follow the story, she shouldn't have intervened and let the boy suffer when he was young. Oh but she couldn't do that could she? She could've just stayed away but she didn't do that did she? So why the hell is she trying to use that as an excuse.
I feel like there's no point to her being reincarnated. She's incredibly weak willed and doesn't stand up for herself at all. It takes a dress and makeup for her to feel confident and pretty? My goodness what a lovely message.
