It is a transmigration/Isekai plot line. The main female lead is also an actress who gets transported into the historical script she is acting in. Very funny like quite a bit of Dream Within a Dream. The Main Lead has his sinister moments. The two main leads have great chemistry.
The Heroine is from the contemporary era but gets transported back in time into a story where she think she knows how it will all play out and does what she can to change things. If she doesn't, she's afraid she will die. The Main Lead is also the "villainous" character.
