Mpreg & omegaverse

I just never understand this gap culture. So seme n uke just a sex friend,but uke is pregnant, there are no say about omegaverse in the intro but it can be that reason. Uke n seme isn't that close bcs they just a sex friend. But seme want to take responsibility in that situation

Idk what is pheromone compability 0% but it appear they're not match each other based on the pheromone. But it makes more fun, bcs enemy to lover story is already rare to happen n now this pheromone thinv. So it's truly intresting. Well indeed they getting closer bcs seme always teasing uke n that makes they have time more
