Tong Yao never expected that getting a milk tea could result in getting struck by lightning on a sunny day, and then waking up in the 1980s. She became a mischievous, spoilt wife of a top-tier doctor from the future. Rather than leading an ordinary life, she was caught eloping and stealing money, and reacted with crying, making a fuss, and hitting walls.Under the hopeless circumstances, she discovered she could understand animal language. While other time-travelers were busy making money to support their families, she was just enjoying the show.“The deputy director's wife accepted five jins of pork from a patient's family. The old couple is squabbling behind closed doors right now.”“The Dean has had a flare-up of hemorrhoids these past few days and can't sit on a chair.”“Mr. Li's wife is a tough woman. That missing tooth on the left was knocked out by her.”“Tong Yao has improper conduct. She used to secretly meet people in the village.”Tong Yao didn't expect the day would come when she would be the talk of the town....One day, Tong Yao heard a stray cat at the door muttering, “Dr. Si is having a date with a nurse in the corridor.”Furious, Tong Yao went to catch them in the act, only to find the doctor was discussing a patient's condition with a nurse who was over fifty. Wanting to run away, Tong Yao found her escape route cut off by the doctor, who backed her against a wall, “So I heard you came to catch us, huh?”Tong Yao never expected the saying, 'Those who always walk by the river eventually get their shoes wet,' to come true.
