I started to get into K-Pop in 2018 due to the KDA Popstars Live Performance of Soyeon for the LOL World Championship.
After rewatching that Performance too many times my YouTube recommendations were pretty K-Pop heavy. With Jennies SOLO which got released around the same time I started to watch a lot of Blackpink content.
After this I warched the subbed 2NE1 content I could find. In 2020 I binged a lot of ITZY content after Parus et ITZY and Wannabe. Then I found Dreamcatcher and watched about all of their content.
In 2022 I went to my first K-Pop concert with the Sunday of K-Pop FLEX and later in the year the Berlin and Tilburg shows of Dreamcatcher's Apocalypse: Follow Us Tour.
I do also listen to Japanese and English K-Pop songs. But I tend to only listen to those who were written in that language rather than translations, since I always get confused and expect the Korean lyrics for translated songs.
