My Husband's Mistress Turned Out to Be My Sister

This is the kind of guilty-pleasure serial that knows exactly what it is. On the surface this is a Romance serial, but underneath it is a story about payback served cold — and "My Husband's Mistress Turned Out to Be My Sister" plays both layers for all they are worth.

Elara gave up her career to marry Damon, caught the infidelity while pregnant, and survived a rooftop fall thanks to her sister Liora — who lost her own child in the rescue. Then a hospital revelation detonates everything: Liora is the birth mother of Elara's son. The show is at its best in the wreckage — two sisters, one child, and a husband who lied to both.

Tropes on the menu: revenge, modern. Episodes are bite-sized, the cliffhangers are ruthless, and the payoff lands faster than most full-length shows manage in a season.
