@WildGrizzlyBear: I don't think that's fair to Shizuko. She has every reason to be wary of Shuri. He is not exactly respectful towards her either. I love Shuri, but he is also very flawed. Remember the end of chapter 4?
@Orion2G: As I read it, Shizuko DOES gradually grow warmer feelings for Shuri. That is what I love about the series: Almost every chapter ends with them growing slightly closer. But I can also understand why you might not like it.
I think it's interesting to look at what the author appears to be saying. Shuri barges into Shizuko's life uninvited, and while he does try to help and protect her and care for her, he is also incredibly possessive and really bad at listening to her. And have you noticed that whenever Shizuko rejects Shuri and pushes him away, she PROMPTLY gets herself into trouble and needs Shuri to rescue her?
It seems that the author is saying: "Girl, you brought this upon yourself by being difficult. You should just be submissive to your man. Look at Yuzuki and Tokoyo! Be more like them!"[1]
Kirioka Sana is definitely no feminist. She advocates very old-fashioned gender norms.
