For MuBank, Inkigayo n The Show-i believe there's eng subs on cable tv jere(the selling point of legal cable tv), but u watched it live streamed on Mnet as far bk as 2015, man tats hardcore. Some of em hv tiny tiny, blink n u miss it English names of the groups/artist so i literally dint recognise em even if i recorded it n rewinded sometimes. N tats in 2019. To learn more i would hv had to google search n in 2019 i wasnt invested enuf/skilled at looking up wikipedia page to read the artists who performed tat day(hmm, i might still not hv learned how to look tat up).
I hv tried to watch in real time, i think starting with Yuri's solo debut, her comeback showcase ig it was of her in a radio/broadcast station i think but the lack of eng subs/my not understanding korean made me give up after abt 10/15 minutes(maybe slightly longer but no more than 30 minutes). Iv not watched any others fully since, not even Gfriend's which had subs but badly synced. I might do so for a SNSD cb tho.
Did u watch TV in korea in ur hotel room, or on laptop, or wats the online booking room site called again, airbnb or equivalent, room? Im curious abt ur travel there which u wrote a guide to here earlier but im too lazy rn to look for it again.
