This answer is most definitely Choi Jonghyun of Tin Tap :D Just like that.

Well, first off...we could actually in all technicality be full blooded siblings. No, not really (obviously), because I'm Italio-Russian-Poli-Sh (short for Italian/Russian/Polish/English), and Changjo is Korean...but we're actually a little more than 9 months apart in age. Meaning that (it'd be uber gross), but we're far enough in age to actually be born siblings XD ♥

But I'd love to have him call me Noona all the time. Changjo is the cutest little awkward kid I ever did see. He's very witty and intelligent, and is incredibly talented, I can't deny. To be able to hang with him day in and day out and watch him grow would be a very special thing :)

He's another one of those biases of mine where I can't think of him as a ual being...just as a sibling XD Plus Sharona would kill me ._.

And that's another thing! By being his actual Noona I could protect him from all the crazy fangirls *cough*Sharona*cough*. But no, I'd love to be able to protect him from the world and all unnecessary risks and dangers. Although it's hard enough with a much younger brother...I guess he'd probably have to protect his Noona instead ._.

LOLZ And there aren't many idols younger than me to choose from. But still...Choi Jonghyun is Noona's little bundle of joy ^^ ♥
