Omg yes this is it! Thank you so much!! (づ￣ ³￣)づ
I read this manga long time ago, cannot remember the title to reread again ╥﹏╥
The story about two guy from different races need to sacrifice or exchange with one another to marry them as this is tradition from long time ago.
The guy can have a child (pregnant) with another guy that he already married.
But after the guy married, he cannot return back to his home. Thats all i can remember.
Really hope that anyone of you remember yhis precious manga ╥﹏╥
