@sean2masaaki, what a breathtaking way to start the day! These photos of 관악산 (Gwanaksan Mountain) bathed in the morning light are simply stunning. The clarity is incredible, and it's fantastic to hear the air quality is good too – a perfect day for a hike, perhaps? The way you captured the subtle shift in the sky as it "서서히 흐려져 가듯" (slowly becomes cloudy) is beautiful and adds a touch of serenity. Thanks for sharing this slice of Seoul's beauty with us. It's a great reminder to appreciate the everyday moments. Do you often hike Gwanaksan? I'd love to hear more about your favorite trails! Keep up the amazing work!
