The concept of the show is to select a group of promising rappers from open auditions and whittle down that number down through various assignments, with contestant survival dependent on the "producers," a group of experienced rappers who also serve as mentors. Eventually the rappers are divided into small teams headed by those producers. From there each contestant will face a different team's rapper in head-to-head single-elimination rounds where survival in the competition is dependent on votes from a live studio audience. In the third season, there was also a "Revival Round" in which contestants previously eliminated had a chance to continue in the competition.

The survival of the fittest is the primary rule in the African wild of Maasai Mara in Kenya. In the land of the jungle of the law, the survival story of Samantha, a single-mother cheetah, is revealed. Samantha struggles with all the hardships for the survival of herself and her offspring. In spite of the adverse condition where she has to find ways to protect her three offspring all by herself from threats of predatory beasts like lions and hyenas, she never gives up easily.

Each of them will have a lease with three terms that they want each others to do for themselves or do together. After agreeing to the terms set out, the tenant give the owner a rent (not explicitly announced), they will jointly sign the contracts and start living together. They will live together for a few days and carry out the contractual provisions, as well as create memories together as friends. At the end, they will sincerely think about the memories with each other after living together, and each of them will separately respond to a survey that they will select "YES" or "NO" to become roommates with each other again; the results are announced shortly thereafter.
