Korean Mysteries

It's a beautiful Spring day here in Korea. It's simply great. It's warm and the cherry blossoms are in full bloom throughout Busan. I went for a walk this morning to check out nature in all of it's glory. What I came across was a mystery. I mystery library nontheless. What is Busan's Mystery Library? I'm not sure. I couldn't find it! Maybe that's part of this Korean Mystery.
