Kim Heenim the King of sassy and snark!
Ren from Nu'est is evil sassy and I love it!
SHINee's Key is so sassy he doesn't even have to speak to make it known. Master of the 'Look'!
EXO's own sassy lil shit, maknae Oh Sehun! He always has a look on his face or a snide come-back at the ready I love him.
This is my list! Agree/Disagree? whatcha all think?! @kpopandkimchi here it is, thoughts?
