Single men and woman live together for 30 days to find love. A panel observes and predicts which singles will fall in love based on dates, text exchanges, and their interactions in the house. Chinese version of Korea's "Heart Signal".

This is the Chinese version of the popular dating based South Korean Reality Show,"Heart Signal" Three women and three men cohabit in a house for a month where they are encouraged to flirt and send other signals of romantic interest. They are not allowed to reveal their age or career until their second day. They can work or go to school during the day but must return to the house at night. They may not directly confess they like or love another single during the show. Each night they send an anonymous text signaling their interest in another single. A panel of celebrities act as detectives and guess who each single will send a text to. During the show, one extra man and one woman join the singles to act as a catfish or disruptor by simply adding new options. At the end of the month, each single indicates who they wish to be with by calling the one they are most interested in. Those that select each other are considered a couple.—leahcubed
