After A Bin loses his memory in a car accident, he wakes up to find a stunningly aloof female CEO sitting beside his bed, claiming to be his wife. The very next day, she brings her household registration book, and they register their marriage. Only gradually does he realize that she is the self-made CEO of the Bai Group, and the woman he helped five years ago, who has silently waited for him ever since. Once his memory returns, A Bin relies on no one. He rewrites proposals, takes on projects, and wins back the ideas that were stolen from him, earning the right to stand proudly by her side through his own abilities.
