Choice A FTW!

haneira, yes it's just a general question ^^ And yep i totally agreed with your statement! ^^

Kai is hot, y, dangerous, fierce..
And Jongin is innocent, childish, dorky, adorable..

Kai is more of a fierce and kind of crazy persona...Kai is...screaming and lust.
Jongin on the other hand is more innocent, tired/sleepy, dorky, easily scared boy next door. It's interesting watching Jongin act as Kai on stage! It's like his alter ego.
(Was this question a general one, or does it have to do with a fanfic? I saw the poll on the main page, so sorry if I am out of context XD )

One is a stage name, the other is his birth name lol
