Happy Together is back with its fourth season. This time, the main hosts of the show, Yu Jae Seok, Jun Hyun Moo, and Cho Sae Ho, visit the stars instead of inviting them to the studio. The hosts bring out the stories from guest celebrities each week, and the viewers will be able to enjoy the talk in various settings. This season is expected to be more diverse as the location will vary each week. Moreover, the hosts are expected to show off their chemistry as they are determined to bring more fun to the viewers.
