There are times when the female lead finds herself being unable to control her actions, which is similar to the "stages" in EY. However, only she is affected by these "stages". Similarly, the actual male lead ends up being different from the original written male lead.
In both dramas, the female lead traverses into a story world that she wrote and finds that she is actually the "evil" second female lead. However, "Oh My Drama Lover" is different in that the female lead loses her memory and her appearance is different in the story world. Furthermore, the actual male lead of the drama is not the story's written male lead.
