Bae Jia has a one-night stand with rich heir Kim Minhyuk, who has poor sperm motility, and becomes pregnant. Due to her friend's and his first love's scheming, she loses the child and dies. Reborn at the moment she discovers the pregnancy, she swears that she will protect her baby and rewrite her fate this time.

To fulfill her grandmother's wish, Kim Ha-eun rushes into marriage—only for her husband to leave for overseas work the very next day. A year later, the company's CEO, just returned from abroad, has a face that seems strangely familiar to Ha-eun. His true identity shocks her. As they grow closer, her guarded heart begins to open. Though married for a year, the two fall in love again, as if meeting for the first time.
