Same time period, same “villainous” ML, same naive yet fighting spirit FL, same need for ML to hide and protect FL without her knowing, same ML head over heels googley-eyed for FL, while FL in love with SML until she realizes how much ML has done for her!

-Républican Era
-Revenge
-The female lead thinks that the male lead killed her dad
-Angst between the leads

Both are light historical romances with the couple falling in love after marriage. Both have cosmetics shops.

Both dramas feature contract relationships (siblings vs. marriage) that turn into true love. The FLs are quirky and endearing, the MLs seemingly cold but very warm hearted. Both couples sell skin care products, and both are wrongfully blamed for causing allergies on the people who buy them. Both are light, fluffy historical romances.

Both dramas begin with the ML killing the FL, then she is reborn/comes back to life. At first she fears the ML but over time falls in love, and the ML softens and falls for her as well.
