[Coraline AU] [Cover is mine!] You and your husband started a new life in a new environment at the Pink Palace. You felt your marriage life drifted apart because of your busy-working husband. He devoted his focus to his work, not even having a glimpse of time to care for his pregnant wife. But soon you set foot into the small door on the wall, you found yourself in a world where things were livelier and brighter, and the man called himself, 'the other husband', a better version of your own. But what everybody says... something's too good to be true.
