Sazukatta No Ha, Oke No Himitsu

Lady Amira's strict earl father decided her marriage to a man she'd never met. She refuses the arrangement by escaping out her bedroom window and almost falls... As she clings onto the edge of the windowsill, she decides she'd rather die than be trapped in her cage. That is until handsome Sheikh Adir comes to her rescue. The two feel an instant deep connection and Adir promises Amira he'll come back for her. Four months later, on the day of her wedding, Adir finally returns and takes Amira away, but for some reason he feels different from before... He tells Amira he only rescued her to humiliate her fiance! Not only that, but he takes her to his kingdom and asks her to be his mistress! (Source: Renta!)
