How about early morning on a weekday? There are only a few days left until you can go to work.
Looking at the moon protractor app, it looks like the angle of the moon is good from Beacon Mound in Ansan, Seoul towards Namsan Tower...
It was around 1:50 in the morning and I knew it was crazy, but I ended up going to Seoul again.
The fine dust was good and the wind wasn't blowing too hard, so I left with a beautiful moon trail and another memory while seeing the night view of Seoul.
I wait for the moon to rise and take pictures of the night view. Even in the wee hours of the morning, Yeouido is busy at night.
