Retired Hero to --- (working title)

Deo Wrij is the youngest duke to the Yale Kingdom. What made him claim the title and position was because he was a summoned hero, who defeated Yale kingdom\'s enemy nation after 2 years since his summon.

With no way back home, Deo enjoyed the life in comfort for since 3 years being duke and his fiancee was the princess. What can be any better?

Except, the finacee was with another man!

After things were resolved, he had no goal in life.

So, why not get a job?
