I mean, I get Yamada is airing her frustrations that she has been accumulating but at least she should already know that he and Moeko are in a study group together for months and they both are pushing very hard for exams (Yamada and Moeko even talked about this recently). So I think she can definitely be criticized based of that knowledge of hers,
Because the problem isn't that he spends time with Moeko, but that he was at her house and didn't even tell her about it. It was just the last straw for her, because he insisted that they stop seeing each other until he passed his exams, but at the same time he has no problem seeing other people. The point here is that he is ignoring her. I won't say she's right, because she decided to put up with it all and then couldn't take it anymore in the end, but what upset her in this chapter is based on limited information, because she doesn't know that he was helping to make a music video for the song “Moving Forward.”
which I did in my previous comment because there are people (also on different platforms) putting all blame on Ichikawa for their overall situation and it's getting a little annoying.
Well, I myself don't like how people on Twitter and Reddit have been making accusations against Kyotaro unilaterally, insisting that he must fix everything and apologize, but as I wrote in this comment section earlier, insisting that Anna is also to blame is wrong (she is also often accused on other resources, in particular on Mangadex).
Let me explain: if it all boils down to Kyotaro being right and Anna having to stop acting childish, then that would simply put her in a dangerous situation. Both adhere to a dangerous and incorrect mentality about what it means to be an adult, and Anna, who openly agrees to all the demands and requirements, even though she will clearly be unhappy because of it, because, like Kyotaro, she thinks that to be an adult you have to blindly sacrifice everything for work, forgetting that they are children, and even if they were really adults, this is the wrong mentality. And considering what scenes she will have in the next seasons of “KimiOku” and the fact that the agency can really forbid her from even keeping in touch with him... she really needs to learn to express her disagreement, it's not always selfishness.
As for Kyotaro, he himself has a huge inferiority complex and tries too hard to do things for Anna. He basically chose this school and is trying to get in to make up for his feelings of guilt over failing the exam, to prove himself because he still despises himself and, in his opinion, this is necessary to be worthy of being with Yamada. He puts his idea of how to make her happy above what will actually make her happy based on his low self-esteem, not realizing that this is not what she wants, which is why Kyotaro is prone to outright self-sacrifice, while Anna herself does not fully understand his feelings, while he tries to fight his own battle (albeit in the wrong way, considering that he risks failing his exams if he doesn't change his approach) and simply expects that he can take the initiative in the relationship without any problems and apologize for the fact that he is the way he is.
And in cases where only one person has to admit their guilt, the communication problem is not solved, but on the contrary, it can become even worse. Their thoughts and feelings are still not synchronized, and to solve this, they need to learn to communicate sincerely with each other, openly express what they feel, and address it all together. If only one person atones for their guilt, then they will simply continue in the same vein as after the end of volume 12.
