This is where Go An-na (Im Yoona) waits for her dad in episode 6 of tvN The K2 (더 케이투) (2016) because it was the first amusement park visit they did together here. But then it’s Kim Je-ha aka K2 (Ji Chang-Wook) who comes instead (pretending he was send by her father). He offers her a strawberry ice-cream unknowing that she has a strawberry allergy and she passes out nearly immediately. K2 performs CFP in episode 7 while his JSS special forces colleagues force their way into the park to get her as quickly as possible to the hospital.
This public park was also seen in KBS2 IRIS (아이리스) (2009).
