Miss Night and Day

After the death of her parents, Joo Ah Ran plots to ruin the family that destroyed hers. She seduces and marries the son of her enemy, Shin Hyun Woo, who discovers her plan belatedly. With a new face, courtesy of plastic surgery after meeting with a car accident, he decides to exact his own revenge upon her.

Blending body-swap fantasy, workplace drama, romantic comedy and serial killer thriller into one prime-time package, the K-drama Miss Night and Day has a little something for everyone.
The serial killer and the killings will leave you guessing till the end.

If you loved the magical transformation and heart warming romance in 'Miss Night and Day' (2024), you'll definitely enjoy 'Perfume' (2019).
This drama follows a middle-aged woman who gets a second chance at life and love through a mysterious perfume that transforms her into a younger version of herself. It's a delightful mix of comedy, self-discovery, and sweet romance that will keep you hooked from start to finish

concept is same that young female lead is suddenly turned to old
due to different reasons !!!
both are fun to watch and have deep feelings!!

The concept reminds me of Miss Granny
- FL turns from Old age to Young age (MG - After Photo clicked it's permanent, MNAD - Day 50 yrs and at Night 20 yrs)
- I like the concept now when the age goes back & forth
