Take the subway to Sinnonhyeon Station. Walk out through exit 4.
Just as you walk out, turn right and walk down the alley for about 100 meters. The first place where you can turn left if you were going by car, not down the first one way street that leads to a parking lot, you turn left into the next alley.
Walk straight forward for about 250 meters. After about 130m, the road will turn slightly to the left, but just keep on going straight forward on the same road and you'll be fine. After 250 meters the road will drastically turn right, but there really is no where else to go but to keep on walking down that road, so you shouldn't be too confused. You walk a few more meters until you can turn left or right, and there, on the left side, is Pledis. It's a white building with a clear sign that says Pledis. If you see Nu'est, or the pledis trainees Seventeen, then leave a comment and tell me about will you?
