While I was at Star Mall/COEX Mall in Gangnam to see the big library, I happened to stumble upon the BTS x Seoul moving billboard. It was quite a sight, but taking photos was a bit tricky, it’s surrounded by a jumble of other ads, so you really have to wait for BTS’s turn to get the full moving shot perfectly framed.

Catching the visuals scroll across the massive screen, even unexpectedly, felt like discovering a hidden treasure tucked into the city. Standing there, waiting for the right moment to snap the photo, it felt like a brief, magical intersection of Seoul’s energy and BTS’s presence, a little moment added to my own Purple Vault of memories from the trip.
