Daily life is harder than war?!
The century-long war between humans and demons ended with a final duel between the Demon King Guest and the Hero, Ash Lloyd. Under the peace treaty, it became mandatory for the Hero and the Demon King to live together as a symbol of world peace.
No right of refusal
Separation prohibited
Lifestyle audits included
Roomsharing between arch-enemies
Under these constraints, the Hero Ash has zero sense of personal space?! He is a master at acting spoiled and is overly touchy-feely?!
Whenever anyone approaches Guest, he cuts in with a smile, barely hiding his possessiveness behind jokes...
The world's strongest Hero has zero life skills and is the world's most in love with Guest???
