Man, I found this chapter awful even though it had good parts. She just flat out raped her. She multiple times ignored her pleads for her to stop and she even said no, multiple times. Clearly she has never heard No, means No. Just switch one of the genders and imagine if Aya was a guy. People would want him crucificdd for holding her down and stripping her and rightfully so.
It just kills the chapter as I liked that we are getting more Aya now. We found out why she puts up walls, another character she has a history with that could get pretty funny in the next chapter and find out why she went to her house. If it didn't have the rape I would have really liked this chapter.
I'll be honest, I have forgotten most of the previous chapters as it has been so long since I read most of them and I am pretty sure most of them were probably pretty forceful but I can have some tolerance to a point if it's manga or if it's for outlandish gags like Gushing Over Magical Girls where there is fantastical stuff like magical girls. This though is just set in a normal world and I am pretty sure their relationship is meant to be nice as they will get together at the end so it really kills the relationship for me if one of the character's is forcing themselves on the other.
Also, on the note of she enjoyed it though. It's still not okay. Having those thoughts is even worse. Enjoying something does not mean you are okay with it. You could pleasure me while having a gun to my head and while yeah I might feelings of joy, that does not mean I am okay with a gun being pointed to my head. Pleasure is not consent.
I really do hope this doesn't continue. I swear if she rapes her again I will really be questioning what the author is thinking. Now though, if this does get brought up later and is actually a plot point and Aya will be called out for her disgusting behavior then I would be more fine with as I have yet to find a manga that does that he rape occurs (normally it is just brushed over as they enjoyed it so it's fine) and we could have a very interesting story. Highly doubt this will happen though.
