Yeah I would've loved to see further explanation of it as well. The story did feel like it left a lot of open stuff it could've explored further such as further development of the Grandma's character(she's mentioned but we never actually see her? why?), depiction of the actual wedding, or the side couple to name a few. The author could of added a few more steamy scenes like the first time they did it, or a scene where the omega is on top, or in general more conflict.
In terms of the omegaverse, the thing about omegaverses is that there is just an overall general rule that authors have to follow. Such as there being: an omega, beta, and alpha with omegas and alphas going through heat cycles. From here the author can pretty much add their own smaller detailed rules. They can be as detailed or generic as they want, that's part of why I think there's so many omegaverses out there.
Cool my first lesbian omegaverse but... it's so weird (?) Like. So do they grow a d or- like- how the f does the pregnancy work lmfao + if the director is an alpha tieing did her v clench with teeth the fingers ? Too many un answered questions even if I like the bare chests
