Good dramas with identity swap/double identity

I need suggestions on this kind of dramas but fairly recent , let's  say from the last 2-3 years . and possibly with revengy plot.

Mask (identity swap)

Goodbye Mr. Black (double identity)

The Emperor: Owner of the Mask (identity swap)

Hwarang: The Poet Warrior Youth (identity swap)

Shopping King Louie (double identity)

Oh My Ghostess (identity swap)

Healer (double identity)
