KBS2s Manhole has released a behind-the-scenes video of the actors both having fun and working hard while filming the drama.
JYJs Kim Jaejoong (Bong Pil) begins by introducing his character as a good-for-nothing. He pulls off several stunts like fighting and jumping over police cars, showing how difficult it was to film that part.
He then turns into a high school boy who prepared a special birthday party for his one-sided love Soo Jin. In the scene, the fireworks he prepared go haywire and end up summoning the police. UEE (Soo Jin) is surprised by the huge fireworks and says, This is like war!
