Is Soo Yeon going to torment Jung Woo? And Hyung Joon is going to help? Is it wrong that I slurp all this dysfunction? I adore Jung Woo beyond measure and don't want this already broken person hurt further but I can understand why Soo Yeon, fractured as she is and not in possession of the facts that the viewer is (though she is so messed up, even if she knew everything, she might still want to hurt JW), wants to go that way. Spreading the pain makes so much sense in her circumstances. As to Hyun Joon - dude, you are kinda freaking me out. Minus the 'kinda.'
Second, have this amazing amazing MV:
