The story begins with Lan Yiwei, a girl from an aristocratic family, falling in love with Li Wan, a man from an unknown family. During their time with him, she hated the golden retriever "Dangdang" and did all kinds of stupid things. Later, he decided to go abroad, but was moved by Li Wan's true feelings. He traveled with Li Wan for three months to relax, and entrusted "Dangdang" to Uncle Zhang. Uncle Zhang treated "Dangdang" kindly, but "Dangdang" was dejected, didn't want to eat anything, and missed his master. Three months later, Lan Yiwei and Li Wan got engaged and came back to Chamberbury to take back "Dangdang". "Dangdang" saw his master and Lan Yiwei and barked at them, but quickly ran to jump into Lan Yiwei's arms and later told about their happy life.
