Gently Dying GD

Somehow, it's not until he's staring at the cold corpse of his Empress that he realizes what he's lost. And somehow, it's not until he's running into the nursery that he remembers their daughter is dead. It's like he's waking up from a dream, only to find himself in a nightmare of his own creation.

If only that woman hadn't enchanted him, if only he hadn't met her...

Or: In which Emperor Jian Li finds himself reborn five years before his Empress' death, in the body of a sister he previously didn't have.

He fully intends to murder his former self.
