Yamaki fanmade MV 

MOSTLY FAKE SUBS
there's no connection at all between the music and the story in the video this time. So... yeah. I think it's self-explanatory and the music is there because I like the song.
Carnival by Jay Chou (园游会)
I don't know why but this is blocked in Germany, apparently? Why Jay Chou's music is licensed in Germany is beyond me.
