Divorce a Ghost, Marry a King

和离！权倾朝野摄政王他不装了

He faked his death. She faked her grief. He returned with a mistress. She left with the fortune. Now at the empire's grandest feast, the man who hid in shadows steps forward, wearing the regent's crown. And the woman they both underestimated? She's holding the only thing that matters: the truth. Adapted from Fujun Jiasi Sannian, Jingcheng Fozi Fengkuang You Ta Pojie, by Qi Huangshu.
