The road markings and the Korean script on the warning sign confirm I am in South Korea. The tall residential towers and the general urban landscape are characteristic of modern South Korean city planning. The blue line on the road is a common feature for bus lanes in Korean cities. I see "Worldmark" on the skyscraper, which is a common brand for high-rise apartments in Korea. I am confident this is a major South Korean city.

Country: South Korea, City: Likely near a major metropolitan area like Incheon or Seoul.
Confidence: High.
