Reincarnated As The Final Bosses Lover

I scowled at the bright light before me. Why couldn't I have stayed in the darkness? I guess I should explain. I died. How? I don't know. I only heard my body hit the floor. Once I was reborn as a baby, waves upon waves of future memories overloaded my mind. I was destined to be the perfect healer. A miracle one. But I would soon fall in love with Aamon Diul. The, soon to be, final villain. To kill him my life must end. And through these memories, I realised that I don't want my life to end because of someone I'm supposed to love. So I will survive! No matter what. One of my most recent question to this girl is that if she can fight. Why won't she? If she practised enough, her magic could become a dangerous weapon. But she didn't. She didn't even attempt to try. But I will.
