Theo Asper was a member of the mercenary guild, who had joined and been expelled from several adventurer parties.
The reason was simple, he was weak.
Wishing he was stronger, he summoned a devil to make his wish come true. But the moment he laid eyes on the devil he summoned…
“I will grant you your wish, but in return I will take something important…”
“Please m-marry me!”
“…Ah?”
His thoughts of becoming stronger left his mind without a trace.
The devil granted his wish, and they became a couple.
“Helvi… Can we hold hands?”
“…Ah, yes. (You’re so cute! Ah… I want to assault you right here and now. As soon as we get home…)”
This is a slightly lewd (?) story of a timid boy and an assertive devil marrying and living happily, even as there is a great fuss being made around them.
