Sheng Xinyue, who had been raised in the countryside, was recalled by the snobbish Sheng family and forced to marry into the wealthy Gao family in place of her younger sister, to perform a "joyous ceremony" for the second young master, who was rumored to be terminally ill. Thinking she had fallen into a pit of fire, she unexpectedly discovered that her nominal husband was the man she had met briefly on the roadside. Gao Shiheng was not actually ill but had a hidden ailment and secretly controlled a business empire as a "hidden tycoon." The two gradually got closer as they went from mutual suspicion and wariness to reaching a cooperative marriage agreement, and in the process of jointly dealing with the conspiracies within and outside the family and the suppression from enemies. Sheng Xinyue, with her extraordinary wisdom and excellent medical skills, helped Gao Shiheng resolve crises time and time again. Gao Shiheng and Sheng Xinyue gradually fell in love with each other during their time together, and finally achieved success in both career and love.
