Growing up, Song Yan and Xu Qin were the best of friends. But as they grew older, their families began to see their friendship in an unfavorable light. Unwilling to allow their relationship to go any farther, Song Yan and Xu Qin were forced apart by their families, never to see each other again. In the ten years since their forced separation, both Song Yan and Xu Qin have worked hard to build the life they’ve always wanted. As fire chief, Song Yan has dedicated his life to saving others. Oddly enough, Xu Qin has also made it her life’s work to save others as an emergency doctor. Though working in entirely different fields, it was only a matter of time before fate stepped in to reunite the former friends. Brought together by their work, Song Yan and Xu Qin aren't exactly thrilled to be reunited once again. Working side-by-side, it’s easy to recognize the growth each has made over the years, but there’s still so much Xu Qin and Song Yan to work through if they’re going to turn this new relationship of theirs into something more. Do they have what it takes to overcome the obstacles before them or is their current relationship destined to be as fleeting as the last?
