This was the first show that came to my mind after watching a small part of EXchange on Insta. They literally have the same theme, of putting some people somewhere so after a certain period they will have to choose a partner. The difference is in that in Singles inferno that somewhere is a desert and the people are complete strangers.

The first season of the same show:)
I also haven't watched the first season, but from the first two episodes I got to understand that the overall rules and the main mcs are the same.
