The airtight pure white room has cold metal devices embedded in the walls. The only exit requires a "life replacement" procedure - the door can only be opened if one party's vital signs completely disappear. Two people who lost their memory were imprisoned here, with only one obsession left in their minds: "My lover is waiting for me, I must live." With their fanatical obsession with the "unknown lover", they launched a desperate game against the "obstructor" in front of them, but they did not know that each other was the destination of each other's dreams.
Concept: When memory is erased, can love still exist?
