I am No. 0314, An experimental subject sentenced to death by a genetic disease.
He is number 0313, my nominal brother. In order to save me, he voluntarily merged with the contact alien species.
He said that we are brothers and sisters bound by fate, but his possessiveness has already crossed the line.
Until I discovered that the life-saving medicine I drank every day was mixed with his blood; during the days when he disappeared every month, he suffered the severe pain of genetic tearing alone.
My life was bought with his pain.
"Want to be free? Impossible." Countless gray-purple tentacles trapped me in his cage. His voice was paranoid and gentle, "Your life is mine. From your genes to your soul, you can only stay with me."
