Yun Rao was stabbed to death after rejecting a suitor's confession. Even after her death, she was bound to a so-called "Devoted Supporting Female" System. So is this supposed to be karmic retribution? She's meant to play a supporting woman who secretly loves the male lead and is willing to die for him. Yun Rao thinks that's going to be hard. After all, in every world, the male lead has been killed by her for one reason or another. Perhaps the villain role suits her better. She would make a very successful villain, since not every villain can keep killing the male lead again and again.
Dongdongba: Warning, you are a devoted supporting female. Stop stealing the villain's job!
Theme: Don't lose yourself in love.
