If I hadn't met you, would the outcome have been the same? When four modern girls travel through time and become four girls of the Dragon King, when the past is revealed, when friendships are betrayed, when she becomes the daughter of the Dragon King of the East China Sea, she finds that her heart already belongs to her family, when her sisters help her in a desperate situation, how does she make a choice? How does a modern girl become the Dragon King's daughter, how does she become the King's woman, and how does she change her destiny?
