In both dramas, there is a theme of rebirth and gaining another chance to change one's life. The main heroine, with the help of a devoted man, mercilessly takes revenge on her oppressors, delivers justice, and transforms her fate.
In this drama, there is also a theme of an allegedly incestuous relationship. The heroine is driven by a desire to avenge her family.
An alleged incestuous relationship is also a plot point here. Both dramas feature heroines who experience amnesia and try to get revenge on their "beloved."
Both dramas feature a forbidden love, supposedly between siblings. In each case, the male lead is possessive, jealous, intense, and completely devoted to the woman he loves. The female characters in both stories want to escape and free themselves — they’re looking for a peaceful life. A noble and decent man tries to win their hearts, but despite that, they have erotic dreams about their 'brother' and struggle with conflicting feelings for him.
