In 1935, Shanghai was a prosperous city where Chinese and Western cultures blended together. Cheongsams and suits danced together, and tradition and modernity collided. Shen Jingwan, the daughter of a wealthy businessman, met Cheng Yuanzhi, an architect who had returned from studying abroad, at a charity dinner. The two hit it off because of their shared love for traditional culture. Later, Cheng Yuanzhi invited Shen Jingwan to visit the Chinese-Western building he designed. The two held an oil-paper umbrella together in the rain, and their feelings for each other grew secretly, but they were both reserved and restrained. Later, Shen's father arranged for Jingwan to marry the banker's son for the benefit of the family, and Cheng Yuanzhi was also asked by his father to return to Tianjin to inherit the family business, and the two faced separation. Jingwan found Cheng Yuanzhi in the rain, and the two expressed their feelings in the rain, agreeing to meet again after each fight for their freedom.
