Lol, what are those tapes? And SM academy? Are they like.... karaoke version of SNSD songs on cassette tapes so you can play them on boomboxes and practice dancing/singing?
The only KPOP I have EVER seen/owned on casette tapes was Seo Taiji's "Nan Arayo", and that was cause my mom bought it for me and my bro.
As for the Hyun Joon-Tiffany combo I wouldn't read too much into it. The celebrity shows in Korea love pairing up people up because it makes for entertaining TV and boosts ratings. The shows are also heavily scripted/pre-planned, so you never know if an artist is really expressing their true feelings or are simply exaggerating, etc. If you've ever watched X-Man or Love Letter, you'll see tons of instances where the MCs try to hook people up and make a big deal out of little things. It's all in good fun.
