I'm not really 100% sure about this but because Kei is a Omega he is able to get pregnant no mater which way. If it would had been an Alpha bottom and Beta top both male then it wouldn' have worked. A Beta getting a Omega pregnant is I think not impossible but you have to try it out alot. Lucky them eh?
Im happy that they end up together but i dont understand why he get pregnant? I mean tsugitsugu is beta right? Enlighten me guys.
