Now that I think about it, do you think the real reason Madoka is upset with the Yuzu (in Sachiko's body) is because Yuzu is acting like Madoka herself? Overly obsessed and wanting to be their everything?I feel like if I re-read the series now it'll make a lot more sense how Madoka treats Yuzu-in-Sachiko's-body
edit: Ok yeah I just re-read the series to this point, recommended
