Amnesia trope is poison

I have to vent my frustration. Earlier I was watching a short drama starring Zhang JinYi and Liang SiWei : two actors that I find hot and who tend to shine in those grey type of roles. Because I am frustrated I am gonna summarise the drama a bit. In the beginning the plot gave a sense of revenge storyline involving two twisted characters with some dash of transmigration (female lead transmigrated into a novel and became the villain). The main female lead had a villainess persona with some violent and maso tendencies : a rich heiress with a complex and traumatic childhood undergoing mental health and needing smoking and medication to survive. She then reformed a bit by the first seconds of the show cause of the transmigration without losing her charismatic bad girl energy. Meanwhile the male lead had that (what we call in French) "écorché vif" attribute (mainly due to the female lead who held him in captivity and tortured him for four years for amusement). So all he has in his heart and mind is revenge against the rich sadistic female lead and you could see during the first few minutes he was a traumatized individual also facing a certain member of his (fallen) family who wanted him deleted even he was a very low point in his life. After a period of hardships (and with female giving him some money as a repayment) male lead managed and become the city mogul. Meeting the female lead again he decided to torment her because for him the four years of tortures and the scars left on his body haven't been paid back (he paid her back the money she gave him at a certain point). Knowing how powerful he became she knew she couldn't run so she kind of gave in and faced the consequences of her bad decisions. Nevertheless, even during that vulnerable time, you could see that she still maintained her natural flavour. Til then I found that lousy micro drama entertaining and I was hooked. Zhang JinYi (girl has a nice body and a lovely face) and Liang Siwei in a hot revenge drama : I am in. Then, "patatra" as we say in French, amnesia trope. Female lead gets hit on the head and lose memory. And she becomes "a sweet innocent doormat" that ends up living with male lead and who manage and melt his heart bit by bit.
