At twenty, socialite Sang Mo was forced by her family into an arranged marriage with Bo Sihan, the most powerful man in all of Beicheng. At twenty-five, just after getting her divorce certificate, Sang Mo died in a street car accident. Opening her eyes again, she found herself seven years later, penniless, with her only possible source of help being this "unfamiliar" ex-husband. After mentally preparing herself to contact him, Sang Mo discovered that the once-unattainable Mr. Bo was now fiercely protecting her under his wings, never leaving her side. All of Beicheng knew that the head of the Bo family held a white moonlight in his heart, his untouchable reverse scale. No one knew that she was precisely the ex-wife he had lost with his own hands; this time, he would never let go again.
