“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?

This is the story of a young man who was reincarnated as a dragon with a near-insatiable curiosity. Initially sparked by questioning his own reincarnation, he quickly gets lost in the endless world of magic, using his deep understanding of advanced sciences to learn the laws and properties of a new type of energy known as mana.However, soon enough, the table would flip, and he would begin using that very same energy to expand his knowledge of science, to the point that he would begin questioning his own understanding of the world.Although not his original intention, with the combination of his intelligence, expanding curiosity, and the 'miracles' that occurred to allow for his existence, he quickly found himself climbing the mountain of strength as if it were a small hill before eventually climbing to a point where it seemed as if he himself was the peak itself.Even if.. that was never the case...There is mild gore, and profanity is 'censored' toward the beginning, but not later in the story.
