Eden began twitching around as the black mist seeped into her. She had a pained expression and made faint gurgling sounds. Eden's eyes bulged and became bloodshot.
She transitioned between a face that showed she was in agonizing pain and a blissful smile. It was as though Eden couldn't make up her mind on whether she was hurting or happy.
Her heart began to beat faster before transforming into something else.
First, it began to blacken.
Then it squirmed around like a parasite, slowly expanding itself. The feeling was quite discomforting, like an itch on the inside of her body. Even if she wanted to scratch it, she couldn't.
Unless she peeled away her skin, that is.
However, the heart was already in the process of doing that. A hole gradually began forming on the skin above her heart, like something inside was crawling out. Eden's vision became blurry, but her mind was getting clearer.
