BTS!
Years back I learnt that BTS rabbit hole doesn't spare anyone. Even being familiar with some idols due to kdramas... but because of GS, disliked even the thought of kpop and avoided it.
Unintentonally listening to BTS songs in the background of a YT video got my attention. And like with every new interest... explored the entire 'genre' of kpop, in the seach of the BEST.
Especially when I read numerous comments under kpop/BTS YT videos talking about how BTS was nothing comapred to the real royalty of kpop... exo, bb etc.
Mind you, I was far from a BTS stan then. After weeks of going through numerous discographies and being bored to death came to the conclusion that kpop as a whole wasn't for me. Except for BTS that is, their music and performances made me a stan.
Much later came to know of twitter, Run! Etc and then fell in love with their chemistry and hardwork too.
