It is about a prince or king, I think. Someone's that noble and in high society. He has the power to cure anyone exchange for money. He has a curse or something like that hurts him. He has these vines like rose vines entangled around his body, every time he cures someone. He doesn't cure people for free, he needs the exact amount of money. He looks for someone worthy the cure. A girl, the protagonist, was sent to him to watch him or something. I think she is a doctor? prophet? I don't know, I forgot. Do you know what's the title of this manga. Many thanks!
