In the small town of Mantuo five years after their separation, Tang Man saw Lu Gang, the man she once deeply loved, among the noisy crowds on the street. The sun suddenly shone brightly, and the lively crowd seemed to be thousands of miles away. He was full of joy but desolate. He had thousands of words but could not say a single word. In the midst of emotion, Lu Gang hurried past without looking back. After parting, Tang Man dreamed of meeting Lu Gang countless times, but none of them would be like this... Such a passing... Trust and deception, friendship and love, in the bustling youth, whose branches are blooming brilliantly and whose flowers are quickly withering?
