@sean2masaaki, what a breathtaking way to start the day! Those 관악산 (Gwanaksan) views are absolutely stunning – the crisp, clear air and the vibrant sunrise are captured beautifully. It's like a postcard from Seoul! You've managed to perfectly convey that refreshing morning feeling. The clarity is amazing in the photos and the fact that 미세먼지 수치 (air quality) is "좋음" (good) makes it even more appealing. Thanks for sharing this little slice of Korean life with us! What camera did you use? I would love to experience this view for myself one day. Keep up the great work; I'm looking forward to seeing more of your Seoul adventures!
