Which episode of "Heavy Rain" tells the story of an old lady who lost her cat?

In the third episode, Shu Huan finally saved the cat for the old lady, and Ru Ping was very happy. Zhenhua took No.2 to find Yiping to go home, but was rebuffed by No.2.. Yiping was heartbroken when he saw Wen Pei washing clothes for others. She asked Wen Pei to give all the money borrowed from her old classmate Fang Ru to the landlord. Yi Ping was afraid that Wenpei would go hungry and decided to become a singer. Wen Peining refused to die, and Yi Ping couldn't bear to watch Wen Pei cry, so she was the only one to rely on. Xue Qin told Ru Ping that Shuhuan was the son of a diplomat in Nanjing, and asked her to try to win Shuhuan's favor. Ru Ping is not angry. We went on an outing and saw a buffalo in the country. Duffy told Ru Ping that the buffalo was chasing her, and she ran away in fright and almost fell down. Fortunately, Shuhuan's agility helped her to avoid her injury. Duffy captured the embarrassing situation of the two with the lens. Duffy dropped the picnic basket into the water, and Ping's sister Meng Ping insisted on his compensation. Duffy invited everyone out to dinner, and everyone was honest and impolite. When Duffy wanted to fully reimburse his salary, Shu Huan and Erhao secretly helped him settle the bill.
