I've noticed that there aren't a lot of Chaekey fanfics out there, so I've decided to make a one shot about them. In this story, Chaerin & Key have been faithfully married for two years and going strong. Lately , Chaerin has been acting strange towards her lovely husband. She keeps hiding something! and Key doesn't know what it is. He starts to wonder if his wife is getting bored of him and having a secret affair,  so he sits his wife down and begins to pull out the 'good cop, bad cop' impression on her, in which he doesn't get the answer he wants. From then he begins to truly wonder... What is his wife hiding?
