MBC's new popular drama, "Greatest Love" is doing so well that viewers can't look away when it's airing. As a matter of fact, they're watching so closely they noticed a "ghost" in the background of a scene where actors Cha Seung Won (Athena: Goddess of War) and Gong Hyo Jin (Pasta) were walking out of a building. Well we all know how rare long, black hair is in South Korea, so can you blame them for seeing ghosts? No, you can't, but you can blame scary movies for conditioning them that way. This was no ghost, just a ninja. And no not the shirtless, pop-star kind I like in my movies, but an ordinary school girl who managed to get caught on camera by accident while they were shooting this scene. Whoops! What else can you expect from the second-most-watched drama of it's time slot? With 17.9% of the nation watching, someone was bound to catch a glimpse of the student who was "just looking for the bathroom" as she got her 15-seconds of fame in this screenshot. What do you think, did this girl really get lost on the way to the bathroom or does security need more coffee? "Greatest Love" is coming to DramaFever very soon! Source: Nate
