Bright line (emotional line): The cowardly concubine Su Wan marries Prince Jing, the "living king of hell". They respect each other like "ice" and test each other, to being attracted to each other and running in both directions in crisis after crisis. Xiao Heng is cold and cruel to the outside world but doting on the inside. Su Wan slowly takes off his disguise. There is no misunderstanding and no third party intervenes in the whole process. The double standard of sweetness and sweetness runs through the whole process.
Hidden line (puzzle solving line): Su Wan sneaked into Prince Jing's palace under the cover of a substitute marriage to investigate the injustice of the Mo family's extermination; Xiao Heng was also secretly investigating the truth about the Mo case. The two went from being suspicious of each other's identities to discovering that they had the same goal and officially joined forces. They peeled off layers of clues to decipher the clues, and finally overthrew the prime minister, cleared the way for the Mo family, and purged the court of traitors.
The two lines are deeply bound: every breakthrough in solving puzzles promotes the warming of feelings, every confirmation of feelings unlocks new clues, and conflicts and sweet pets go hand in hand.
