Theo Asper is a member of the mercenary guild, who has already joined and been expelled from several adventurer parties. The reason is simple, he is too weak. Wanting to become stronger, Theo summons a demon to make his wish come true. But the moment he laid eyes on the demon he summoned… the dreams of becoming stronger left his mind. “I will grant you your wish, but in return I will take something important…” “Please m-marry me!” “…Ah?” The demon granted his wish, and they became husband and wife. “Helvi… Can we hold hands?” “…Uh, sure. (You’re so cute! Ah… I want to ravish you right here and now. Just wait until we get home…)” This is a slightly lewd (?) story of a timid boy and an assertive demon lady marrying and living happily, even as there she causes a great deal of fuss around them.
