Producer Park Sang Hyuk of SBS variety show 'Roommate' talked about the close relationship between cast members 2NE1's Park Bom and After School's Nana.

When asked if the two were actually close, the producer replied, "Park Bom and Nana's relationship was the most unexpected. �Right now, they got a lot closer. �To tell the truth, after my first impression of the two, I thought that they might not get along to the very end. �However, they surprisingly get along so well to the point you could view them as the best of friends."

He continued, "Nana seemed like a city slicker, so I was expecting her to play the trouble maker role. �However, to my surprise, she had strong consideration for others. �I wonder if that's how the two became close quickly."
