That's a new one so, I can't say it's omegaverse or something similar but uke's pregnant about 4 months. And it seems like only imperial family members can make males pregnant. Seme's crown prince and uke's second guard of military. So, you can see a strong uke too. In first chapter uke fainted and after that learned about pregnancy. Seme doesn't know still. Uke has a lot of person close to him too.
