I've seen this concept before (Ratman sort of, Dramatic Couple) but I never get tired of it, especially when the female is comically clingy and jealous.
Is it me, or did this manga start the whole elfxorc vanilla thing? I remember reading a manga about some elf into scat after this came out a while ago then there is the one about that warrior elf trying to bang her asexual orc husband.
So is this ending? Because it seems like a really good place to end before it becomes too long and suffers from the degradation that always happens when manga outlive their "golden period".
(Laughing) The ending of that first chapter got me. Honestly thought the ending would be "thanks for saving my younger brother! By the way, MY WIFE would also like to thank you!"
