While different time periods, both are historical dramas in which the ML is engaged or married to a cruel/unlikeable woman who then ends up replaced by an identical woman with a very different personality who he falls in love with. Both FLs have a matching jade token (either to each other or to the ML) and their switch/initial replacement was when they were young.
The story is of a heroine Su Xiao Xiao who deliberately approached Fei Ming Xuan and staged a classic mismatched love scene with him. However, at the same time, the Tang and Song Dynasties also wandered between Su Xiao Xiao and Fang Min, intending to use Su Xiao Xiao to bring down Fei Ming Xuan. A plan within a plan is quietly played out, and true love finally finds its own palette in each drama.
