I feel like if he ends it, Reiji will just start another cringe as fuck series. And you know he'll get it serialized immediately, because the magazine and editors all acknowledge his unfortunate and annoying ability to somehow milk a raisin (or to use a more serious phrase, blood from a stone lol), along with the fact that, no shit, the inner monologues he writes for Kazuya are a major factor in this series' popularity. Not to us, obviously, but to the Japanese audience, or at least it seems that way considering 75% of each chapter is Kazuya mentally shitting himself over Chizuru blinking and thinking there's some hidden philosophical meaning to it that could end world hunger or bring world peace. And if it's not that, it's him mentally jacking off to Chizuru's outfit that given day/chapter.He is cursed. If he stops Kanokari (or it gets cancelled) Cthulhu will swallow the earth. Lucky for us, curse makes him immortal.
Edit. As ex-reader turned to comment section enjoyer, I think he should end it. Just to release rest of you from the hell. Also world is kinda cringe place rn
I legitimately have never seen another mangaka or author or writer in general so blatantly in love with their own creation that even if it may not have originally been intended, he turned Kazuya into more than a reader's self-insert and went full-blown Reiji-insert. Anytime a Kazuya monologue starts I pretty much tune out and skim cause I've been reading KanoKari for so long (it hurts to admit to it, cause it really has been a long time that I wouldn't be able to deny any accusations of being a masochist lmfao) that after 301 chapters, I can't stand to sit through another one of Reiji's creepy one-handed writing/drawing/describing Chizuru's current look and basically read three pages of him trying to justify why he's wanking it while he's writing, and just skim to where the chapter continues with the story and he's done fantasizing about his drawings. And by then, there's only two or three pages of story left, and it ends up just being gag panels or some kinda joke that feels forced as if someone caught him sticking his dick in a printout of Chizuru with a hole cut in the mouth and crotch areas pasted or taped to his worn out dick sleeve and then tried to make an awkward or bad joke to lighten the super awkward mood after getting caught lol
Anyway. Even if he somehow finally agrees or decides to euthanize KanoKari, we all know the ending would cause one faction or another to riot and send death threats to Reiji, his editors, the magazine, the publisher, and the overall parent company that owns all of them as well lol
And at that point, even without them, he would still probably end up getting another series serialized immediately, and even faster if it ended up a KanoKari sequel or even spin-off, cause not only Reiji, but his editors, and the magazine all know and acknowledge KanoKari's unfortunate popularity and the fact its a cash cow (which also kinda unfortunately sheds light on the majority of his Eastern/Japanese reader base), so KanoKari related or not, Reiji won't have trouble getting serialized again, and because of KanoKari, he knows he can repeat the entire series' outline and general road map and its gimmicks and know he'll get another hit, or at least a steady stream of positive reviews and votes on the reader popularity polls.
Plus he's also already got another series being serialized right now alongside KanoKari (Shiunji-ke no Kodomo-tachi; The Children of Shiunji Family), and while it's not the same as KanoKari, it's still a Reiji romcom series, but this time about seven siblings who learn they're not related by blood, and every single sister is in love with the oldest brother, while the second brother is out getting it from an actual unrelated classmate lmfao
It's only at 17 chapters, and idk if it's still released as tankobon volumes or if it got serialized after the first volume got a really positive reception and reviews, but the pacing is like 50/50, where the chapter-length stories or even multi-chapter stories are paced decently, but the overarching plot feels like KanoKari-tier progression just lurking in the shadows ready to troll everyone the second Reiji drops an "implied to be major" cliffhanger, only for it to be negated and resolved in the first page of the next chapter and ultimately irrelevant and unimportant lol
Anyway this went on for far too long lmfao sorry for the wall, /r lol
