It's about this girl who died and transmigrated as a queen candidate. Its about how everyone thought she poisoned herself to get the rulers attention but in reality, she was truly poisoned by someone else. Anyways she meets the chamberlain I think he was like the ruler's secretary but in reality, he was the actual ruler masquerading as the chamberlain. She and him started to get close and I remember in one scene she accidentally met the ruler in a garden, and she kissed him or something and he ended up eating her rose flavored candy that was in her mouth. In one scene the ruler said to get rid of all the roses because so many candidates kept dying on the rose beds or something. So, she decided to take all the roses and started up a business with them making rose wine and rose candy. Later one of the candidates tried to kill her by giving everyone a pendant but hers was said to be cursed anyone who where's it will die. But it turns out some kind of beast guardian was inside and started to protect her. Anyways the ruler and her pretty much fell in love but it turns out she was slowly dying; I think because it was not her real body.
I am remembering a lot of things but that is just some of what I remember so can anyone tell me if they know the title of this?
