Singer NS Yoon-G recently posted a casual shot to her Twitter account with close friends Jia from miss A and actor Seo Ji Suk.

Sitting together in the back of a van, the three celebrities exude familiarity with each other and beauty that shines even through their casual clothing.

"They look like siblings," a fan commented, while other pointed out that Seo Ji Suk looked like a dependable older brother taking care of his two younger dongsaengs.
