Getting his heart trampled on by a bet during high school, Byun Baekhyun swore he'd never let anyone get "that" close to him ever again. He transformed himself from an average lovesick puppy of a student in to a guyliner wearing lady killer. Being in his second year in college he thought everything went fine. No signs of him falling in love and what not. Girls and even boys chased after him, but that was that. Not once did he let his guard down, always keeping his emotions in check. After an encounter with a new student though, he felt his guard waver. His unbreakable barrier suddenly became, well, less unbreakable. And slowly he felt that all of the emotions he tried so hard to lock away before suddenly emerge. Will he try to build up his barrier again or slowly let this certain someone break it down?
