Unfortunately it's just 2 short films/MVs...
The first focus on Xia De and the second on Ryan Hsu. The symbolism are great, the acting are intense and the music are amazing. But since is small and quick you can't expect for deep development or even truly understand the plot.
Everyone have their own interpretations and theories about the story, but what I know it's that I really wish so much that we have a HIStory4 about this...
Since I watched HIStory I have a particular interest in the twins from HIstory3 MODC, so see Xia Em and mainly Xia De here in this crossover with Ryan Hsu from HIStory2 CL, was very satisfying!
