LOONA TV #59 is the fifty-ninth episode of LOONA TV and the first episode of YeoJin's arc.
At 5:20AM on December 23, 2016, YeoJin introduces herself as the fourth member of LOONA while at the airport before their flight. YeoJin tells the camera she is 15 years old (14 internationally) and that the other members call her "Bean" (콩). HaSeul insists YeoJin looks like a lentil bean due to her size, and HyunJin demonstrates that she is almost a full head taller than YeoJin. The members take a picture together, and then tease HyunJin about her selfie habits.
