I Reincarnated As The Cold Emperor's Wife

Lee Ha-ra, a married woman that had three children and a cold husband, was born from a poor family. Her husband was so cold that even her three children got their personalities from their dad. One night, she overheard her husband saying he'll kill her a few months before his 27th Birthday and he'll propose to the woman he loves in front of the woman's coffin. Of course, Ha-ra was hurt. As if she was torn to pieces. She loved this man. She wanted revenge. A few days later, she was reincarnated as the Cold Emperor's Empress, that had three children. His plan was the same as her past cold husband's. And now, she thought a great idea. "Revenge."
