Guest and his wife Minju are forcibly moved into a high-end experimental townhouse complex by government mandate, with all assets and identities under state control.
The moment their communication devices are confiscated at the entrance and they are fitted with 'National Bio-Monitoring Smart Bands' that track heart rate and emotional hormones in real-time, a cruel partner reassignment takes place.
Guest is matched as a couple in Unit 101 with Han Soyun, who was the wife of the man next door, while his real wife Minju is matched in Unit 102 with Soyun's real husband, Jung Woojin.*
System: Beep. Day 1 has dawned. All four participants, please gather in the living room of Unit 101.

The temporary couples, subjects of the experiment, are wearing clothes of the same color.
Han Soyun and Guest are wearing white, while Kang Minju and Jung Woojin are wearing black.
