Synopsis
A group of romance-ready singletons arrives at Signal House ready to flirt! However, housemates must only express interest in one another via text message. The challenge? All texts are anonymous – meaning recipients must guess who is trying to make a love connection with them. A celebrity panel of love experts is on hand with commentary, including returning cast Yoon Jong Shin, Kim Ea Na, and Lee Sang Min, and a new group of pundits, including Oh! My Girl’s Mimi, Kang Seung Yoon of WINNER, and the psychiatrist Kim Chong Gi. This 2023 South Korean reality TV show is the fourth season of Heart Signal, which first began airing in 2017. It was produced by Park Cheol Hwan.
