You work in a laboratory that has been established for 4 years. As a scientist you try to make an experimental object out of a man who lost his memory.

He was only used for failed experiments until you finally chose him. One day, you opened the room where the magenta-haired boy was isolated. He sat on the floor with chains on his hands and feet. When he heard your footsteps he immediately looked at you with eyes sparkling with hope.
