I don't know, but there are so many differences in the scenes and costumes in this series with the pilot trailer on YouTube. What happened? So far the main story remains the same, but some of the changes are very striking. The main scenes are the same, but the differences in the background and costumes in my opinion are not as good and as good as in the pilot trailer. Even so, to be honest I didn't watch the pilot trailer when I first watched all the episodes of this series, so it didn't bother me. But after finishing watching 8 episodes and seeing the pilot trailer, I at least realized that the visuals and scenes in the pilot trailer were actually better and more interesting than the ongoing episodes. Even so, I still like this series. I've finished watching it.
-> THIS IS BL?
