Which Korean Artist یا Korean Group Was Your First?

سے طرف کی "First" I mean a Korean artist/group that got آپ to really love this genre. For example I was first introduced to K-Pop سے طرف کی PSY's "Gangnam Style", but I fell in-love with K-Pop during EXO-M's Overdose era, therefore my "First" was EXO-M.
