On the day Lu Wan reports to her unit after graduating from military academy, she nearly falls during a surprise training exercise on a stormy night. When Sheng Ye grabs her hand and pulls her up, he becomes the one and only point of attraction in her military career.
It turns out that during that stormy night drill, he deliberately slowed his pace and secretly adjusted the route. He had turned “helping her” into a mutual act of devotion all along.
But the “deal” she made with her father keeps her from taking that final step. When she finally gathers the courage to “negotiate” with him, her father threatens to take his own life. She returns to the military camp, where she and Sheng Ye become strangers.
During the three years she is away, the countless reunions he orchestrates let their love endure and grow stronger as they both mature.
When the truth, buried under misunderstandings, finally comes to light, it turns out they had simply been protecting each other in their own clumsy ways.
At last, beneath the witness of the military flag, every crack becomes a pattern of heartbeats on their military marriage certificate. More dazzling than any medal is the love they wrote in camouflage and scars, a love that came late but never strayed from its course.
