This manga was just all sorts of confusing and biologically nonsensical lol. The usual ABO universe already has enough illogical traits on its own, but when even more complications are added to it just to satisfy the author's mpreg furry fetish it simply became far too silly and far-fetched to be taken seriously even for BL's standard. The art also did not help making the confusions any clearer, especially in the last chapter when the "big twist" was revealed.

But even without all those absurdities with the worldbuilding this story is still painfully average stuff at best. Characters barely have any real personality established besides their species/ gender roles and what's entailed that they love to keep drilling on and on into our heads. The romance didn't feel romantic while the smut just became gratuitous at some point. It was a very bland yet messy read; really a weird experience.
