Hi! I'm trying to find a manhwa. The FL has these special powers (something like a saintess) and I think she had to get married or else she would die. Her fiancee (i think) ends up going somewhere with a fake saintess during the time she has to get married and she almost dies but the duke (ML , I think he had white hair) married her to save her life...
