On a rainy night in Haicheng, Shen Juan reunited with Gu Yan, who had disappeared for seven years, in his usual cafe. The fiery bonds of the past were buried by time. When they met again, one was a calm and reserved business elite, and the other was a mysterious returnee with a sense of alienation. The air was filled with unspoken questions and unspeakable complex emotions.
Shen Juan's company project was suddenly blocked by the mysterious organization "Night Falcon", and the person sent to investigate disappeared mysteriously, and the crisis was approaching step by step. Gu Yan's unexpected appearance does not seem to be accidental - he knows "Ye Falcon" well, and even stepped forward at the critical moment, sneaking into dangerous situations to save people alongside Shen Juan.
As they join forces to fight against "Ye Falcon", the truth about Gu Yan's departure without saying goodbye seven years ago gradually comes to light. It turns out that his departure concealed the protection of Shen Juan, and "Ye Falcon"'s conspiracy has already tightly entwined the fate of the two of them. Suspicion and trust are repeatedly pulled together, past pain is intertwined with current dependence, they get closer in crisis after crisis, and re-examine each other's feelings in the process of uncovering secrets.
When the final trump card of "Night Falcon" is revealed and the dust-laden secrets are completely exposed, can Shen Juan and Gu Yan put aside their grudges and truly become each other's armor? This reunion, which involves danger and redemption, will eventually make them understand that some bonds, no matter how long they are apart, are destined to be intertwined with blazing light again in the torrent of fate.
