What The Hell ? !

Hu Hui Fang is a top-tier Shanghai prosecutor: brilliant, glamorous, and permanently annoyed by incompetence.
Luo Chang Ming is an elite defense lawyer: calm, incisive, and equally annoyed by her.

They've been rivals since law school.
They live in the same neighborhood.
They argue in court, run into each other in elevators, and pretend none of this is strange.

Then they take on the same corruption case.

The building holding the final evidence catches fire.

They die.

-or so it seems.

Their life complicates when they woke up in another era, another life, with another identity.

What The Hell?! (CN title : 你干嘛！？) is a historical romcom about fake dating that refuses to stay fake, competence dropped into a feudal system, and two people who would rather fix the mess than rule it.
