I don’t think I have too many precedents for what I’m about to say but the whole “gruff guy who finds a kid becomes a begrudging parent” always never worked w a woman bc she would never be depicted gruff enough and even if she did it’s weird to force motherhood on a woman who’s gender nonconforming and also it’s funnier doing that to a guy bc societal repercussions irl make that more appealing to the masses bc of gap moe (you know what I mean). It isn’t gap moe to fulfill gender roles I guess
That being said, I think there’s definitely a through line here where there’s a young woman (usually) thrust upon motherhood with something inhuman/beast like as well. This feels like it could date back historically even before all this hot buzzy media trope of “sexy masculine man as dad” was even a thing but yeah. Rosemary’s Baby is kind of huge with this tho you don’t get that relationship until the very end when she sees her baby. And I guess I’m thinking specifically of I Want to Hold Aono-Kun where *spoiler* that green baby thing shows up, metaphorically or not.
I think the main thing here is a juxtaposition of the Madonna and child here. Whereas both are young beautiful and “right” (politically, societally) if one was exchanged with something off [masculine non-traditional father is equivalent to the mother’s beastly child here lol] then we get that trope in the reversed gender.
Something awesome which we haven’t seen yet is what I mentioned above w the gruff woman having a child but again I would need that to be extremely layered to work without being super misogynistic
