Lee Jieun is scared and she hates it. She doesn't want to be seen weak and pathetic, so instead she hides it. But fear is always there. It's always itching in the back of her mind. It's only a matter of time before someone finds out. So what happens when Kim Jonghyun, a guy she had never even spoken to before her eighteenth birthday, starts to see past all her defences. Will she still be able to conceal her fears? Or will she face them?
