I found some individual performances on YT from these two posters. Between them I found most of the top skates except for Ah Sun Yun's short program...It's basically decided, I don't think KSU is going to do something as radical as differ from tradition. Yelim, Haein, and Junhwan will be the singles team. Min/Eaton as our only ID team automatically get the spot but I have no idea what's going on with them.
I don't want to assume anything but after almost completely missing last season because of boot issues then not being able to train because of the pandemic... I'd have to think that she's semi-retired now. I say semi-retired because she may appear in events like the WSF when they get to happen again, we'll have to wait and see.
As for videos on YT, I haven't actively searched for them but my tesoro Younghyun's fanpage has a Youtube channel with his two performances (SP and FS), and my darling Junhwan's FS is here.
Edit: @surimi, check out gabb's channel(the one with my darling's FS), she has done great work by uploading all videos of the seniors
These links probably won't last long as these posters tend to do a quick hit and then remove their skates.
