“Hmph, my dumb big sister is in danger!” A mischievous grin spread across his face. “Hehehehe... this gives me the perfect excuse to finally use this treasure I’ve acquired but never bothered with!” He rummaged through his belongings, carefully selecting various items. “A bit of this... and this... and a dash of this.” Boom!

Now, all I need is a compatible host for it.” Years later... “Did I overdo it?” he wondered in awe, watching as his creation wreaked havoc, conquering world after world with ease, as though stealing candies from children.

“Pretend to be my lover and join the social circle.”

Selena, the top star that had the entire world’s attention, was suddenly warped to Northern Duke’s land during an accident while filming. Kalcion, the Northern Duke that saved her from the infernal beasts, offers Selena a chance to go back home in return for collecting information in various social circles by pretending to be his lover. Selena quickly accepts Kalcion’s offer, but…

“Why in the world can’t you do this!?”
“Don’t you think that the answer to that should be obvious to you, the actress, not to me, the duke?”

There was a critical problem. The Northern Duke’s acting skills are horrible!

“…Let’s change the plan. I’ll seduce you instead.”

And thus the contractual relationship between the two started. Will Kalcion’s acting skill improve first, or will he start to have true feelings for Selena instead?
