Yellow Boots (2012)

Both main actresses are frame for something they didn't do.

both have the same female lead actress and involve an intense revenge story. The evil psychopath of a protagonist (a.k.a. second female lead) destroys the female leads life in her selfish greed and both dramas involve some serious husband/boyfriend snatching and hidden birth secrets. Both dramas are very similar and equally intense providing one very satisfying revenge story

Both female leads go to jail for a crime they did not commit and lose their child because of it.

Both have a delusional sister in law and I do find some other similarities like the second lead female blaming everyone except herself....

both have the same objective , the revenge on people who have destroyed their lives !
