A friend of mine at high school was utterly obsessed with BTS. She would come every recess and ask me who I liked the most and such, and one day I got tired so I decided "imma check them out so at least I know what she's talking about". This was during RUN era, and that's a f*cking gold era so I got into it. Still, my attention span lasts 1 month but then I discovered all the sub-genres and other groups/bands, and I just fell in love. It was such a huge thing filled with possibilities, like, even if I get bored of one group, there will always be hundreds of other ones, and that's gorgeous. There is so much variety, that's what I'm trying to say, and Korean entertainment shows aren't about the juicy gossip, and I genuinely enjoy that because I can get to know them better and understand them as artists.
Although I got into this genre with BTS, the group that probably made me fall in love with kpop was SEVENTEEN and later on NCT. Now I'm just a mess so there's no definition, but next in the list is definitely iKON.
