Oh yeah I remember that now. Plus him being nicknamed puppy. And I can see the whole thing with his visions of Alex and her ability to calm him down as a sort of "Found my life mate" thing. Though the concept of real Wolf monogamy is somewhat exaggerated, it's still a fairly popular trope in werewolf fiction.
The hints to the MC being a werewolf is part of why I find the bad outcomes to all aggressive choices mildly vexing. Every time you do a bad/aggressive thing it's either a nearly immediate game over, or it's just as immediately made clear you've denied yourself game content that would have followed either immediately, or down the road by damaging the relationship with that character.
I liked the idea in the beginning that only Alex can reign in the beast inside the MC, at least initially. The idea that if Alex aint around, everyone around the MC is one mistake away from a really bad day is an idea that can provide a lot of good story content and even sexy scenes. The MC's a little too in-control most of the time compared to the story's initial setup, and you're immediately punished/denied content if you want to indulge his more aggressive side when the choices to do so present themselves.
Mind you, I don't object to the MC following the "good path". Just don't present the illusion that the dark path is an equally viable way to play the game. Just strip out the choices and make it purely linear. The good path is well written enough to justify it being the only path through the VN
Sidenote: if the MC is a werewolf, I think he should be a Teen Wolf(MTV version)-style werewolf. Most computer animated werewolves I've seen look awful. Just give him some yellow, orange, or red glowing eyes, maybe fangs and claws, and that's it. I vastly prefer the big hulking monster Crinos forms of werewolves mind you, but have not seen any Models for that kind of werewolf that would look good in 3D form. And since it's meant to be an erotic story anyway, just go with the toned down version of a Werewolf that was seen in MTV's Teen Wolf series. If a giant monster wolf is gonna be used, use it only sparingly, for the big horror scenes.
Assuming the MC's does turn out to be a werewolf of course
