TVXQ, Super Junior, SHINee, BigBang, 2PM made it possible for your current favorite boy groups to even fucking debut.
SNSD, Wonder Girls, Kara, 2NE1, T-ara made it possible for your current favorite girl groups to even have a stage to fucking stand on.
Mirotic, Sorry Sorry, Gee, Nobody, I Am the Best, made it possible for your current favorite hits to even be played outside of fucking Korea.
4th gen stans especially continue to stay petty and jealous that 2nd gen is the golden age of kpop that is still loved today while 2 years from now no one will care about the current groups and the music they are releasing. They are as forgettable and as disposable as the tiktok era that gave birth to them.
