After the final shoot of a drama series, it is normally difficult for the crew to gather again as they all have their own busy schedules. However, drama director Kim Seong Yun calls upon the cast of the titles he directed and decides to shoot a variety show. The actors of Love in the Moonlight, Itaewon Class, and The Sound of Magic have gathered. While they take a trip down memory lane of the drama they took part in the past, they also meet up with other actors of other titles. Fifteen young actors and actresses enjoy their retreat with good food and fun games. Not only do they enjoy looking back at old memories, but they also make new ones with new friends.
