My Dear Destiny (2020)

Both MLs have the superhuman ability to convert to an animal and the FL is the key to ending their plight

Both are lighter dramas with a FL who comes from a different world and enters the body of a girl who has died, taking over her life. ML is royal, suffers from some medical condition, and is initially antagonistic/threatening toward her, but she is the only one able to help/cure him. There is scheming within his family to replace/kill him.

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.
