Flip The Game, Love Takes Over.

Two modern best friends are reborn as enemy princesses sent for a political marriage, secretly suspected of being spies. One marries the cold Prince Joel Scott, the other the cunning Prince Bruce Scott. Both princes remain wary—even attempting to eliminate them. But soon, they discover that the so-called spy is a book-obsessed innocent, while the “naive girl” they assumed her to be is a sharp manipulator. With that, a chaotic yet sweet war of misunderstandings begins.
