Classiest K-Pop Idols?

[202020]

My classiest pick would be BoA. She's just so mature, pleasant, respectful and classy lady. 

 

 

Also, I saw a thread a user made about how Taemin threw shade at SM and these were posted. I thought this is such a smart and classy way to throw shade. Most people would be a raging mess but he's so calm and collected. He knows how not to step on the wrong foot, still be savage but in a classy way.
