In 2014 I was watching the mama awards live and I saw there block b vs bts battle fucking amazing, one of the stand outs of the performances that night. After that I started to actively look them up and realised I knew a couple of their songs already (just one day and boy in love).
It's like I fell into this bts rabbit hole and I could never get enough content. These days I'm not as concerned as staying on top of all their content, I just check it out if it catches my interest. Its all there if I want to catch up at any point, but I always make sure to watch their comeback stages.
