Yez her about to rape him should not be romanticized or even normalized. I think the author make a good pointing by making him remember Namia. Different side of the same coin. Yez, he could be gentler. But in fundamental level, he did nothing wrong. It was a self defense or self reflex.
I agree. I do have some doubts shed just kill herself like that. But upon thinking about it. I believe they both have one thing in common "will to live after countless sufferings". Kiska gets his will to live out of years of build up anger. And Ageha gets her will to live out of waiting a prince charming coming to save her. After centuries being sealed waiting, you can bet her expectation of her prince charming is getting way too high farther than to the moon, especially after Kiska complemented her cooking, it skyrocketed her expectation even more! Shes even willing to compromise to be his second. And after getting caught in the flow, having her prince charming looking at her disgusted, realizing what she had done, she realized she cannot fix what she had done. Her centuries waited prince charming is now beyond her reach. You can see her feeling the guilt. I think a typical Yandere would still force herself even after that. and now losing her one will to live, she has nothing else to live for, thus she finally take the act to commit.
The only way he can save her, or prevent her from commiting is by communicating her that he wants to starts small or somthin. But uhmmmnnn upon reading the title, I kinda doubt thats gonna happen. And Im not gonna expect him whos been bullied to that extend to be able to communicate that properly as well. But we'll see how it goes.
All this is my thought. I could be wrong. The author might be pulling phycological manipulation yandere bere. Idk. We'll see how the story goes.
All and all this seems to be a typical suggestive chapter at first. But, if what I had presumed is the case for it. I think its a pretty well thought out chapter after 4 chapters of building up their will to live.
