Living Together in Empty Room

Living Together in Empty Room, also known as My Unexpected Housemate, is a 2017 South Korean television program starring various artists. After premiering its pilot episodes on January 27 and 28, it officially replaced Duet Song Festival and began to air on MBC on Fridays at 21:50 (KST) starting April 14, 2017. The last episode was broadcast on March 23, 2018.

Format
The program revolves mostly around celebrities who live alone or those that are interested in becoming roommates with other celebrities for a short period of time. The participant's house that the roommate(s) temporarily live in becomes the landlord, while the other member(s) are referred to as tenants. Each time there is a new living arrangement, the first order of business is to go over the lease agreement as a group, specifically, the section of the contract where each person lists up to three terms for their time together as roommates. The terms can be rules/guidelines for the roommates to follow, but usually, the terms are activities that each person would like to experience altogether while living as roommates. Once everyone has agreed upon each others terms, the contract is signed by all parties and an acceptable amount for rent is negotiated that the tenant(s) will then pay the landlord before they start living together roommates. They will live together for a few days and carry out the contractual provisions.

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. This survey is only symbolic, and not decisive, i.e. all of them select "YES" doesn't mean that they will be roommates again.
