Liu Mianmian was pushed by her aunt to marry Jin Wang Xiaojin in her stead because her aunt Liu Qingyan eloped during her wedding. For three years, she adhered to her duties as a substitute, drank "contraceptive soup" every day, and secretly saved money to prepare for her escape. Unexpectedly, she got pregnant unexpectedly, just as her sister-in-law was found. In order to protect herself and her unborn child, Liu Mianmian planned to be buried in a sea of fire, and escaped south with her maid. In fact, Xiao Jin had already fallen in love with Liu Mianmian, the wife he was marrying, and he designed his sister-in-law to elope just to marry her. The "contraceptive decoction" was also a good way to regulate her body. After learning that Liu Mianmian faked his death and ran away, Xiaojin immediately chased his wife and intercepted her on the cargo ship. After the truth was revealed, Liu Mianmian put down her guard and worked with Xiao Jin to expose the Liu family scandal.
