Let me start out by saying that there's nothing wrong with stories that are more low stakes and limited in scope - maybe cozy little romantic dramas aren't the flashiest entries, but I think these kinds of plots are just as valuable as anything else, and to be honest, sometimes I look forward to these more than grand epics or suspenseful thrillers. Usually what makes one of these so interesting though is that the lack of a high-stakes A-plot allows for a more detailed inspection of the characters - who they are as people and what they mean to each other. Ultimately, I agree with some of the other recent commenters here in that this feels like a great foundation for a story, but right now it feels like just a foundation and there seem to be some missed opportunities to build on that and make this premise really compelling.
Implementation of Theme:
We've certainly covered this category here, and in multiple ways, to boot. We have William as an imagining of a wasgo, a figure from Canadian First Nations folklore, and then the holiday/festival Gealach a' Bhruic, which gives some (fictional, I think?) folklore specific to the Scottish badgers. Both are well integrated into the narrative, and I think this does more than enough to meet the ask.
Presentation:
Decent category for this entry, if not particularly mindblowing. We get some of the best presentation right off the bat with the CG of the old wedding video - I love the little blur effect and how that scene builds intrigue for the rest of the VN (even if the wedding theme loop was a little short and repetitive). I didn't notice the music much for the rest of the story though. It kinda felt like the definition of background music, which isn't always the worst thing since, y'know, it is background music, and that's always better than being obtrusive.
Other images were pretty solid as well, both in the sprites and the couple other CGs we got (I liked the tail wag for William too!). Still a few typos and other mistakes in the text, but this felt much better proofread than your last May Wolf, so that improvement is great to see.
Story/Writing:
So like I said at the top, we have a good foundation here, but I feel like we're only scratching the surface of what we could do with this premise and these characters.
I think one way to frame this would be to focus on the "whys" for these people. Like, okay, we have an arranged marriage and our leads feel kinda awkward about it, but is this a normal occurrence in this universe's Scotland (we get that it's normal for wasgo, but not necessarily anyone else)? Whether it is or not generally, how strange would it be for that arranged marriage to be gay (like, with a typical hetero arranged marriage, the calculus is pretty simple - one family gets a baby factory with good genes while the other gets a fat dowry. Does it matter to these people that their arranged marriage can't reproduce)? Is there any judgement from the local community about the gay arranged marriage?
This extends down to more specifics about the characters too - why did William's family conceal that he was male? Why didn't Brock's family ever ask for a photo or anything? How do these people care about being forced into marriage generally? Is their sense of cultural obligation that overpowering? If so, why? Why does Brock feel so lonely about Gealach a' Bhruic (yes he moved out of his parents' house, but he mentions extended family getting together for the holiday, so why couldn't he still do that? It's not like he lives far away)? Why has it taken the leads this long to have a conversation about the arranged marriage, other than William's hockey career ending prematurely (noting again that if William didn't agree to this, there would be much bigger concerns)?
I know that's a big list of questions, but I hope that gets across how much more ground you could be covering with this premise. The story right now is pretty short, and there are so many places where you could expand and really flesh out these characters. This goes for the writing style as well - there's some simple sentence structure and telling-not-showing here, and there are some real opportunities to stretch your legs with the style and really set the scene.
One other structural comment here - there's a brief perspective switch from Brock to William, and I'm not sure what we get from this. This isn't something that ever happens again, if I recall correctly, and we effectively learn the same things twice from both perspectives - the marriage was arranged to bring good luck to Brock's family at the cost of William's hockey career. The only thing we get that's different is that William doesn't resent Brock for it, which would probably be better to reveal during their interactions together anyway.
Creativity:
There's definitely some creativity here with the types of folklore that were adapted and integrated into the narrative, and the concept of a gay international catfish arranged marriage could be really interesting, but I think this really just needs a bit more of a push to really flourish. Keep sticking with it - this is still good progress from your last entry and I think you're on the cusp of bringing your talents together to create something really special.
