“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.
