The spelling/grammar is good. I didn't notice anything except this one line that bugged me
"Oh... God. I hadn't heard about that." or "Oh, God, I hadn't heard about that." reads better. Especially with the content of the scene.
I didn't mind a few of the stuttering parts, but I know a guy that uses ... instead and I found those kind of shutters much more natural to read and closer to IRL nervous "can't focus on what I'm gonna say". This is a MAJOR personal opinion though.
Overall the story is pretty interesting, though perhaps the MC should say a bit more in the beginning on why he's completely used to seeing animal people. It makes sense later, but the fact that he doesn't even mention one thing about Carla being a dog is... well, actually it's kind of refreshing in a way, since it shows that anthro-human interactions are commonplace, but since MC mentions stuff like his physiotherapist being a shark, at least a remark about her being a cute dog person would be nice.
Bridgette explains much of the background/lore/world, but there's quite a few details that confuse me, and one of them is a major plot point!
So, Bridgette says they need hybridization, or both races will die out in 3 generations. Uh, why? one of the issues (I think) is that human-anthro unions will only produce one species. That sort of makes sense, but wouldn't that just mean human male-anthro female and human female-anthro male relationships would have to happen to maintain equilibrium? And even if that didn't work--I get it would go against the concept--but couldn't they just mate within species groups? Some clarity on this part would be greatly appreciated!
As someone who's had to deal with a family member getting a catheter, that scene was NOT appealing in anyway shape or form. I get it, it's a H-game and it's an excuse for the nurse to admire MC's balls, but trust me, that's the LAST thing the MC would be thinking about getting one of those yanked out of his cock. Can't really offer any alternative suggestions other than MC having a sponge bath or something.
MC has to be assigned partners. I get that it's the whole point, but the fact that none of these people bring up the fact that MC could just give sperm samples is so silly. These are his co-workers/scientists, at least one person would bring this up (especially if they like MC and want him for themselves.)
MC being a suspect on top of everything is dumb IMO. I get you wanted the cop characters involved, but it would make more sense that the city has him under protection. Him being a suspect should be something that doesn't get revealed until much later, or only if you become friends with the cops assigned to you. Again, this is just a personal option. I think the "I need to clear my name" adds way too much to an already pretty stacked premise.
I have a few other questions, but that's it for now.
Overall, it's a cool premise/setting for a story, and I'll be looking forward to watching this progress, even with what I mentioned.
Good luck on the project!
