*UPDATES*
Ah! I forgot to mention it! These pictures are NOT from the novel! These are separate pictures by Ya-he Audio! They make drama CD and make pictures of the characters! Usually Korean BL books don't have characters on the book cover (not that I know of…). If you press 'Jangryang' or any authors on the TAG, you can see the actual book cover!
I like how they did it… If you are secretive about reading BL, Korean BL book covers are way to go! LOL No one will know those books are BL unless they read it, and they are pretty too! Hahaha.
Yeho, Kill the Lights, Monsieur Park… all of their pictures are from the audio company like Ya-he or ACO. Except for Black Butterfly… because they didn't make that into drama CD…:( I hope they do someday….
