‘Your child is born. You don’t know your child… … .’ A man who lost his memory of the woman he loved before the marriage proposal, Jung Ji-heon. A woman, Jeong-oh Lee, who she had no choice but to think to him that she had broken up. The two meet again after 7 years. And again, the man’s hot obsession. “You have to put it aside. I will never let you go.” Instinct is more accurate than memory, but he doesn’t know yet. She knew he had a pretty child who looked half and half of hers.
