Although some of you may have already caught on, it seems that Kim Min Sun, Nich Khun's fake "girlfriend" on Mnet Scandal, has dated actor Kim Bum in the past. In the second episode of Mnet Scandal with 2PM's Nich Khun, the couple joins Min Sun's friends for some late night drinking.
As the night gets older, one of her riends brings up the talk of Min Sun's ex-boyfriends and, even more stupidly, mentions that she has dated a celebrity in the past. Although Kim Min Sun repeatedly says she doesn't want to tell Nich Khun who that certain celeb-ex was, her friends dropped a big hint anyway, busting out with Boys Over Flowers' OST "Almost Paradise."
One of her friends later brought in "Ga Eul" as another hint for viewers.
