There is an invisible institution in the world: the Administration of Life.
It does not exchange lives or start over again, but:
Life Rental
You can rent someone else's life, and you must pay it back when the lease is up.
But there is one absolute rule:
The more glamorous your rented life is, the faster your original life will rot.
Someone else's good fortune is a temporary tenure,
Your doom is a permanent overdraft.
