Yeees some Grace's pov!!
I think it's very interesting to see more of her. She confirmed that what Kenzaburou is doing is things she wouldn't have said out loud, which means she thinks about it. So I guess that this experience will make her a more genuine and honest person, who doesn't hide what she thinks.
It's also very interesting that it's her grandma that made her break free from her cage. Not her dad, her mother who came to the school festival, her brother, her maids, her friends, but her grandmother. We've been hinted that her mother is a person who's very important for Grace, and I kinda thought that it would be her who would break her cage. But her grandmother makes more sense because Grace knows her better. She heard countless stories, read many books about her, and even when meeting her she felt like this inaccessible person. But the fact that she isn't, shattered Grace's reality, it proves that you can be an amazing person without being a perfect being.
I wonder if her mother will be the reason why she will take her body back.
Her wanting Kenzaburou to stay is very realistic: until now she was just a passive viewer. She was seeing his actions but she wasn't trying to actively learn from him. If she were to take back her body know, would she be able to act like the Grace they all know? Probably no.
