Trying to find his way back to civilization after treasure hunting for days, Lang finally spots a village in the distance but collapses from exhaustion. Waking up, he finds an elf woman, Heina, sitting next to his bed. She is the one who found him and treated his wounds while he slept.

Lang discovers that the entire village is full of women, and Heina reveals to him that he's in an elf mating village—a place where elf women go every 50 years to strengthen their blood by mating with other races. Now Heina wants Lang to choose three women to mate with!
