This apartment provides free food and accommodation. There is only one thing that the tenants need to do - each group of four people must select those who need to be evicted from the apartment and receive punishment at any cost, so as to form a society and maintain its operation.
Intention: Why do human beings become human beings? I don't think just a physical body is enough. Their emotions, interactions, love, fighting, compromise... Who can break out of the apartment cage and finally reach the top?
