This is not paradise because if it was, we’d be able to love each other without any problem. However, we are not the same. You are a person of the light; I am a person of the dark. You are Jekyll, I am Hyde. We complete one being, but we were never meant to be together.

“This experiment should never have happened!” a middle-aged man wearing a white gown said as he slammed his fist on the table. Ignoring the pain it shot to his fist, he glared at each and everyone inside the room. “We should never have continued this. We achieved nothing but pain and misfortune.
