In an episode of “Sisyphus: The Myth,” Seo Hae (portrayed by Park Shin Hye) was seen celebrating her birthday in an amusement park post-nuclear war in the far future. She then also went with Han Tae Sul (portrayed by Jo Seung Woo) on her birthday, when they celebrated in the present timeline, 2020.
The place is called Yongma Land, and is actually an abandoned amusement park that closed in 2011. However, the place opened again for those who would like to visit the location.
Dramas such as “Alice” and “More Than Friends” also filmed here. Plus, K-pop stars like TWICE, BTS, and GOT7 had photoshoots in the Yongma Land. TWICE, in particular, filmed their debut MV “Like OOH-AHH” in said location.
Yongma Land is located in Jungnang-gu, Seoul.
