Miss Granny

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.

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.
