The Healer Consort

Shirai Ran was just your average nurse in her old world, but after her unfortunate demise, she found herself reincarnated into Sekkakoku—a kingdom where imperial courts hold immense influence. Now living as Byakuran, she decides to use her memories and modern medical knowledge to cure the sick and injured. However, it's not long before rumors of the "great mender" with incredible powers reach the ears of a certain Prince Kuryu. In a shocking turn of events, the emperor-to-be snatches her away and gives her an order—become his consort, and cure him of his peculiar illness! (Source: Manga Up!
