this and Black & White are both still a healthier relationship than My Cute Little Kitten.
I think "My Cute Little Kitten" is in a uniquely weird category of it's own, since I don't think Morinaga is trying to make it toxic but it's probably her strangest written relationship. Where it feels like she somehow made it unhealthy on accident, I have no idea.
Black & White is horrifically violent and abusive, and includes rape. So for me at least I'm not comfortable comparing them.
Lastly this series is an intentionally toxic back and fourth, and while I don't know anything about the source material so far this manga doesn't go anywhere nearly as far as Black & White, but I don't really think it's comparable either.
