Who Is She (2024)

The similarity of these drama is that in both of the drama the main lead will have a new body and also a chance to make their dreams came true which they cannot achieved during their youth of age.

Both stories explore transformation, specifically involving age. In "Miss Granny," an elderly woman is magically transformed into her 20-year-old self, allowing her to experience youth again. "Miss Night and Day"involves a similar transformative element, where characters experience life from a perspective they wouldn’t otherwise have.

The Similarity is that, Both the drama is about a second chance of life. Not only that both included being an idol having a second chance. Thank you

FL's both get a second chance after doing evil deeds in their first life. Also they will performs a music band. The dramas are connected by music too.
