Kim EunMi is a very arrogant & selfish person. That is, in the outside. She doesn't like being attached to people & caring about them. To her, the world is her enemy & people are it's soldiers. She is in a never ending battle with the world. But all she actually ever wants is peace. It wasn't her choice of being like this, her past made her become who she is. One day, like a cliché, a new neighbour moves in. Surprise surprise, he's a boy. An idol at that. To make it even more cliché, EunMi doesn't know he's an idol. Like I said. She sees the world & it's people as her enemy. Henry Lau, a bubbly, caring, chill person tries to break down her metal walls. As if trying to break her out of prison. With little experience with emotions, will EunMi conquer all her fears?
