Singer BoA reveals her friendship with actor Kim Min Jong.

On July 16 BoA tweeted, "Cool guy Choi Yoon~ It was great seeing you~ His clear skin that a twenty year old would fall for! Good luck for the remaining two weeks!" with a photo.

In the photo BoA and Kim Min Jong are posing with "V"'s in the air, showing off their friendship. Kim Min Jong especially stood out, with a face that would never pass as one of someone in his forties.

Kim Min Jong and BoA are both a part of the same agency SM Entertainment.  Internet users responded to the photo, "You two look like brother and sister," "How heart-warming," and, "I can't believe there are only two more weeks of 'A Gentleman's Dignity.' Sad!"

Kim Min Jong has been playing the role of Choi Yoon in the SBS drama "A Gentleman's Dignity." His romance with Yoon Jin, who's seventeen years younger, has been gaining a lot of love, just like the other couple Jang Dong Gun and Kim Ha Neul.
