Same 'freak'wency ahh couple

The story is very fast paced, to the point it's kinda absurd. They meet, they fuck, they move in together and get.... Married? In a span of a week, I would assume. I didn't even kno this was omegaverse until the side story, which makes me unsure if it was originally omegaverse or they had an AU switch in the side story. Also the ML backstory is talked about very briefly and is used to explain his erratic behavior and yandare tendancies. MC seems to be perfectly fine with the ML's behavior, lowkey would have wanted an explanation to that (besides that he is lonely and that ML is cute) The story currently really cute and both of them seem to love each other, you could say they are a healthy couple tho that might be a stretch. Hope to see this update cuz I'm very curious what's gonna happen.
