Synopsis：This is a sweet romantic story about a pair of lovable rivals. To escape her mother’s constant pressure to get married, Song Nanqiu signs a one-year contract marriage with Jiang Yanzhi. Cold, composed, and highly efficient, Jiang Yanzhi treats everything by the book. Song Nanqiu believes their marriage is nothing more than a mutually beneficial arrangement—until one day, she is subjected to a routine inspection at a bar and unexpectedly runs into him while he is there handling business. Afterwards, he takes her home and sets strict rules to keep her from getting into similar situations again. As they spend more time together, he quietly stands up for her whenever she is wronged, and he becomes visibly lost when she takes off her wedding ring. Little by little, they both find themselves falling deeper into the relationship. Yet the “one that got away” in Song Nanqiu’s heart remains a barrier neither of them can overcome. It is not until the very end that Jiang Yanzhi finally discovers the true identity of the person he has been jealous of all along.
