The May 5 installment of KBS2TV's 'Unnies' Slam Dunk 2' featured Jeon So Mi and the rest of the 'Unnies' crew on their way to Busan via a train.
As soon as they got off the train, the women shouted with joy "Wow, we're in Busan!"
The members looked around the rather deserted station upon entering, when Jeon So Mi claimed with a cautious Busan dialect, "Aren't there any zombies around here?" referring to the flesh feasting film 'Train to Busan.' With that, Kim Sook followed up with, "Yeah, you girls have to watch out for them zombies!"
