At night when the autumn rain knocks on the window, Cheng Feng, who delivers food, always stops at the street corner and looks at the light on the top floor of Lu Group that stays on until late at night. Five years ago, he was the bright academic master and Lu Yu's firmest promise in his youth; after a family crisis, he became a "deserter" despised by everyone, and she became a sharp blade in the business world that stood up from the ashes.
When they met again in the lobby of the Lu Group, she sneered with red eyes, and he lowered his head to hide his old injuries - the gun scars on his arms, the joint pain that always occurred on rainy days, all telling the story of the past that he had deliberately erased. She used a letter of engagement to trap him by her side. Is it vindictive and difficult, or is she unable to hide her longing for him? Is he forbearing in his humble job as a handyman, a self-exile that he doesn't dare to approach, or has he already included her in the defense line of his life?
When the schemes of business rivals entangle Lu Yu, and when enemies from his mercenary days come to visit him with the code name "Maple Wolf", the truth buried in lies and blood will eventually burst out on a rainy night. Only then did she realize that his "betrayal" was the redemption he had paid for with his life, and the calluses on his palms contained the rain of bullets he had endured for her; only then did he understand that her meanness was the result of her hatred of iron, and that the hot milk she kept late at night had never lost its temperature.
Will the rain stop when the maple leaves fall? A lone wolf with a blood debt and a rose reborn from the ashes. In the smoke of business war and the shadow of the past, can they peel off the cocoon of love and hate, and let the missed time grow back into love in each other's scars?
This is a tug-of-war about concealment and forgiveness, a battle wrapped in the smoke of business war and destiny.
