Because This Is My First Life|Gyeongui Line Forest Park — The Old Tracks Under Yeonnam

The rails went underground. Seoul laid a park on the scar. Gyeongui Line Forest Park runs 6.3 kilometres from Hongje Stream toward Hyochang, ten to sixty metres wide, finished in May 2016, a year before the drama aired. The Yeonnam stretch is the one people nicknamed Yeontral Park.

Creatrip and the Korean Wikipedia location list put date scenes here: the linear lawn between Hongik University Station and the residential alleys of Yeonnam-dong. Street musicians still set up where the sleepers used to be. Cafes face the path. In autumn the ginkgo goes yellow on a schedule the production could not have improved.

Exit 3 of Hongik University Station points you toward the trees. Exit 7 points you into the Hongdae grid. Walk the park first. The drama used this ground because it is what a Seoul date looks like when nobody has a car and both people still have to be at work in the morning. The line is gone. The walking is not.
