HP: Lin Daiyu's Life at Hogwarts

I'm obsessed with Voldemort and Bellatrix, and I can't help myself... All I can say is, this pairing... is toxic! T_T Lin Daiyu, who died young, was the Crimson Pearl Immortal Herb reincarnated to repay a debt of gratitude. After shedding the tears of this life, she should have returned to the Ninth Heaven. But through a twist of fate, her soul was sent to another time and place. There, she found a loving, happy family unlike the one in her previous life, and a childhood friend... And him, whom she met at the most beautiful time in her life.
