Gapyeong Pension Village

Multiple episodes — Sun-woo's neighbourhood

📍Gapyeong-gun, Gyeonggi-do

The upscale pension village in Gapyeong used for the drama's fictional Gosan neighbourhood — the affluent small town where Sun-woo's perfect life is systematically destroyed. Its mix of wealthy residential compounds and scenic countryside suited the drama's contrast between surface beauty and interior rot.
