The road markings and the style of the modern high-rise buildings strongly suggest an East Asian urban environment. The green painted lane markings are characteristic of South Korea. The architecture and the general layout feel like a planned business district in a major Korean city. I am fairly confident this is South Korea, likely Seoul or a satellite city.

The signage on the buildings is clearly in Korean (Hangul), confirming my initial assessment. The presence of the KB Kookmin Bank logo is a strong indicator of a major commercial area in South Korea. The architecture and the specific style of the pedestrian guardrails are very typical of Seoul's urban infrastructure. I am now quite certain this is in Seoul, likely in a business-heavy district like Yeouido or Gangnam.
