Seoul dominates for career opportunities with 70% of Korea's international jobs, but a one-bedroom in Gangnam runs ₩1.2M+/month. Busan is 25-30% cheaper, has Haeundae Beach, world-class seafood markets, and a growing tech scene — ideal for expats who want Korean city life without Seoul's intensity.
