i dont think its because of the backlash, she's just genuinely interested in writing good stuff with depth. it's like this with her other works from the same time period, just not as goofy. you can even see in early chapters from back in 2016, introduction to some character plots that are eventually given more depth as the manga progressed, like with itome showing desire to be monogamous with akemi and having half a page of his face to focus on how he felt in chapter 5. call me a d rider but that's taking a lot of credit from ogeretsu tanaka.
That's exactly the point i was highlighting with my examples, i don't think it's slop. It's a whacky introduction for goofy characters that were meant, *from the start*, to be further developped in later chapters.
Now I can't know how far she meant for this to continue at this point nor how much of it she planned, but it's clear there was setup from the start. Another example, aside from itome, would be shikatani looking at a letter in chapter 5. We find out in chapter chapter 16.2, that this was from "shou-chan," his ex-friend he had a crush on and who hurt him. Thus allowing for the author to dig more into his thoughts.
If that's not convinving enough. She has work earlier than yaribu that would maybe be considered more "mature." Allat to say: I don't think you're giving her enough credit.

Those people on the Internet need to stop mischaracterize this manga saying its about rape and cp. There's so much more depth and an actual layered characters and yes i cried at this chapter.
