Both are historical dramas in which the FL and her child(ren) are murdered by her scheming royal husband and his other consort. She then finds herself a few years in the past and resolves to take revenge and change her future with the help of the emperor's brother who he also murdered by poison in the previous life.

Both begin with the FL and her unborn child murdered by her evil husband. The FL then gets a second chance (soul swap vs. time travel) and becomes involved with his brother and begins to take her revenge.

Both are mini dramas/ads with the same actor and actress playing the lead couple in similar roles and plot.
