In the city of the future, memories can be legally deleted, and the dead can briefly reunite with the living in the "trans-death connection."
Su Jin is the emotional recorder of the "Echo Archives" and is responsible for cleaning people's memories.
She thought she was just a bystander until an old woman who applied to be forgotten brought an old photo——
And in the photo, it's her as a child.
When technology and memory intertwine, the truth emerges.
At the end of the sea, she finally understood: some memories of being sacrificed would not disappear——
They just turn into echoes, waiting for you to come back somewhere you thought you had forgotten.
Purpose: To explore the meaning of memory, forgetting and love.
