Has it not been Yuu being taken advantage of in the beginning, Touko wouldnt even consider having romantic relationship with anyone, including Sayaka. Touko becomes the way she is now with the help of Yuu’s. Whereas Sayaka sees nothing’s wrong with the way Touko is from the beginning, doesnt really now what kind of self inflicted battle Touko has with herself, and thus that’s how she came to look up to Touko as she is the reliable, smart, pretty President Council.
Has Sayaka known, how it’s all just a facadè that Touko put up, unreliable and fragile Touko; would she still think Touko is her ideals?
