Female lead goes to another "dimension", and everything starts from the beginning. Both female leads know what is going to happen and tries to change it. In Legally Romance, FL goes back in time 11 years to when she was still a college student and this time, she tries to fix her life. In the Romance of Tiger and Rose, the FL gets trapped in her script and tries to make her story stay on track. In both dramas, the female leads try to set the male leads up with the second female leads but fails to do so. Both dramas are light and funny.

Starts with an arranged marriage with a cold general. The female lead characters (FLC) were not favored children (General's Lady: FLC was a concubine's daughter while Sleepless Princess: FLC was the king's adoptive daughter). In both dramas, when the FLCs married over, the generals were suspicious of them. The problems that arise between the lead couples were similar too: misunderstandings, bickering, divorce, etc. Both shows also focuses on a investigation that has to do with a family member's death in a fire. When you are watching either, you can see the similarities between the dramas, but they have their own unique storylines.
