This person did an arrangement of that piano ost part that plays when Yuuri and Victor meet up again at the airport, they said they will post a tutorial if the video gets 150 likes, so like it up! (Not on Tumblr, got to go to the actual video on YouTube!) Its such a good arrangement too…this channel (Blackchaos Vortex) does pretty good arrangements of anime osts, so subscribe if you want to see more!!!
