Yu Luojun was a trumpet player at the Shanghai Movie Star Club in the 1930s and was known as the "Prince of Jazz." He is very artistic and emotional, but he is a bit weak. The rich family permitted Miss Ru to fall in love at first sight and at first sight. Due to the huge difference in family status, their love was strongly opposed by Xu Fu. Keru and Yuluojun resolutely eloped to Suzhou. They depended on each other, and Xu's father later accepted them. After the outbreak of the Anti-Japanese War, Yu Luojun and Ke Ru lost their mother and son in the chaos. Yu Luojun took a boat to Hong Kong and then moved to Singapore. After many mistakes, Yu Luojun never saw Ke Ru again. Later, she married Lin Xiu, a kind-hearted peasant woman. Ke Ru always insisted on her love and rejected Zhou Yuguang, who had always loved her deeply. After more than twenty years, Keru finally met Yuluojun. However, things are just like people. Jun Yuluo is in a dilemma, but they finally understand that their true love has been around for many years.
