Ji-eun's been keeping a secret. A secret that no one but her family knows, not even her best friend knows. Having to hide such secrets will come with a cost, and sometimes you never know when the secret's out. 

Daehyun's been keeping an eye on someone. His best friend. She's been acting weird lately but he does not know why. Eventhough he asks, she will always say the same thing. Just what the heck is she hiding from him.
