New love : Back to X?
About
Back to X is a dating reality program where ex-couples reunite in one space to find their true feelings between a new love and a past flame. Participants move in with their respective exes, but initially, no one knows who was with whom. While living together, they may be drawn to a new person or find themselves wavering toward their ex again. Through the anonymous messaging system 'BACK SIGNAL' and the 'X ROOM'—which only ex-couples can enter—they confront their sincere emotions. In the end, they must choose between New Love or Back to X. For three weeks, what will your choice be?
