On a night of pouring rain, Jiang Wanjuan is set up by her scumbag lover and treacherous older sister, and nearly goes from future Princess Consort of Huai to a lowly concubine.
She’d rather find some random man to be her antidote than give herself to that scumbag. He disgusts her!
That’s when Xie Ran appears before her, weak and suffering a relapse...
One is a frail young lady whose betrothal was broken off so her fiancé could marry someone else; the other is a frail prince whose bride-to-be broke their engagement to marry someone else.
One faints whenever she’s wronged, while the other throws up blood whenever he’s bullied...
And yet, one of these pitiful souls acts delicate and weak by day, but can kill with a single stroke at night.
The other is quiet and taciturn in public, but more evil than a ghost in private!
It’s only after they “cough up blood” their way to the top that everyone discovers they both have hidden identities!
