Killed by the Crown Prince Again, I Toss a Grenade into the Eastern Palace

[Goofy, ambitious heroine vs. obsessive, scheming Crown Prince]

[Substitute marriage + bickering couple + both pure + dual Systems]

The legitimate daughter of the Marquis's household, abandoned for over a decade, returns home only to be sent to the Eastern Palace as the Crown Prince's consort.

The Crown Prince is short-lived and brings misfortune to his wives. Everyone says she's being sent to her death, but that's exactly what she wants. A short life is great! She's only here for the seed. She'll have a child, become the Empress Dowager, and enjoy a happiness no one else could understand.

There's just one little problem: the men she once let go, including the Crown Prince, princes, and generals, all want to kill her.

But, unexpectedly, why have they all ended up at her feet?
