She was the only one immune so we needed her to be able to get the antibodies and try to create a cure or vaccine.

"So... How does it feel to be the hero of the world?"

I asked her in a joking tone while separating the samples of her blood.

I must admit that at first I was envious of her, I couldn't believe that she was not affected by the disease, but over time I got used to her.
