So I installed this, and when I pressed "launch" it brought me to my folder which consists of all the MP3 files, arts etc. So I thought, like Vol 1 to 3, I just have to press the 'Watch Now' in the store page to stream the video so that I can watch the subbed version. But for some reason volume 4 doesn't have that button in its store page. Google isn't helping either. Any suggestions?...

I dont even know what this is? are these drama CDs part of a game or just an original radio broadcast?

Wasn't a perfect launch, but its all here, the complete story! Congratulation!
