pretty much since i first got into kpop someee 5 years ago? but only started being more consistent about it a couple years ago. it's mostly a loooooot of self study, i took some beginner classes while i was in uni since they were available to me but haven't studied it in an organized environment since, tho i do eventually want to get back it into it!! unfortunately it's currently really hard finding available classes that i can fit into my work schedule :(
