After rebirth, I was entangled by the Regent

Rebirth + exclusive love + double purity... After rebirth, Nan Mu felt very emotional. In this life, she no longer thought about the unreachable family affection, and no longer obsessed with the love between men and women. She wanted to use her unique medical skills to save the world. What? The person she loved wrongly in the previous life was also reborn and kept pestering her. And the brother who abandoned her in the previous life suddenly showed her kindness? Did they rebirth together? What's more frightening is, why did the regent who didn't appear in the previous life look at her like this, as if he wanted to eat her...
