On the topic of old videos, I rewatched hana ni nare from NHK 2012 and I was struck by the expressiveness in all his movements.
Also, he immediately shifted from the melancholic-yet-hopeful aura of HNN to PW’s rebellious bad boy vibe xD (But seeing him do the pistols pose in the HNN costume was the best combination!)
Really, I’m so glad I discovered Hanyu back in 2018. Now I get the chance to relive all his achievements while he’s still competing.
