In the humid, sweltering summer of Nanping, Lin Nian, a young girl with a bitter past who struggles on her own, meets by chance on a rainy night Jiang Huai, a down-and-out young master expelled by his family and covered in wounds, and the two become companions and share an old tenement building. The boy and girl, both full of scars and bristling with thorns, spend day and night together, healing each other in their straitened, ordinary daily life, and a passionate yet bittersweet love grows between them. The huge gap in their family backgrounds and their families' scheming, wrapped up with misunderstandings, force them to part in pain. When they meet again after six years apart, Lin Nian has shed her youthful inexperience and shines independently, while Jiang Huai has taken charge of the family business and his obsession has not faded; all the regrets of the past are resolved, and after going round in circles, they finally run toward each other after years of wind and rain and stay together in happiness.
