Twenty-six-year-old master’s graduate Su Wanqing is on a rural research trip when a bus crash sends her soul back to the 1980s! She binds herself to the all-purpose rural System and gets a loyal big yellow dog named Wangzai as a bonus. His only flaw is his obsession with licking her feet. As she searches for a way back home, she uses the System to establish herself in the countryside, but keeps running into trouble. Fortunately, Wangzai protects her. Two years later, she runs into Shen Yan, a 22-year-old university student who transmigrated in the same crash. The two search for a way home together, overcome the age gap, and embark on a May-December romance amid melodrama and warmth, facing challenges and life-changing choices as they rise to the top.
