Jiang Zhi and Shen Qingzhou grew up together on the long streets of the old district. She was a clever, stubborn architectural designer, while he was an heir to a powerful family who always kept the big picture in hand. Years later, they reunite, and she beats him on a project he leads. The two go from being "siblings" in all but blood to rivals at work. He once protected her, but now he corners her at every turn. She refuses to accept handouts, even tearing up a check rather than bowing her head. As business interests collide with tangled emotions, and stolen-design scandals and family opposition threaten them, they go from clashing to standing side by side, confirming their feelings in the pouring rain. In the end, the old street becomes a cultural landmark, bearing witness to the happy ending of two equally matched lovers. Childhood sweethearts can be equals, too.
