Kim So Hyun is Close with Yoo Chun JYJ

Kim So Hyun is a new rising child star. She usually do antagonist role, such as The Moon That Embrace The Sun and Rooftop Prince.
As we know, little So Hyun was shooting in the same drama with Yoo Chun, Rooftop Prince.
She has role as young Se Na / Hwa Young in the drama.
And looks like they're close enough these days. We can see it, in account twitter, that people say as Yoo Chun's account. A lot of his tweets mention Kim So Hyun.

Just like to found they know each other, they look match in the picture :)

Anyway...
It's just two episodes left from Rooftop Prince and it's getting more interesting.
Hope you not miss it.^^
