A lonely young man suffering from a terminal illness has a mutual affection with his own shadow who has self-awareness.
It coexists with the same origin and is bound by life and death. When he lives, he traps it, and when he dies, he will perish together.
A secret love that cannot be seen from the light of day, a fateful sadomasochism that is destined to destroy both parties.
Everyone in the world said that he was lonely all his life, and only the dissipated image remembered that they had stayed together with their souls and sacrificed their lives for their love.
Concept: A sadistic love affair between a sickly boy and his loyal dog Shadow
