We all knew the Seven Deadly Sins, which consists of the sins of Pride, Greed, Lust, Wrath, Envy, Gluttony and Sloth, which are now represented by Seven Devils in this world.   And Chaeyoung is one of them.   But she decided to run away from her fated curse and she tried to live a normal life, despite of her curse becoming worse and worse which makes her more demonic.   Until she meets this angel-like girl in her work place.    

The mansion where the mighty snow queen lived is about to get more interesting. There's a burgular in the attic. A girl in the snow queen's mirror. A sparkling dust upstairs. A wrong catch in the frame A trapped animal in the aquarium.  A ghost in the storage. An intruder of the ice cave. A last customer of the mansion. So join us, where nothing is normal. Because that's what makes this mansion light up.

"I'll shine for the two of us" "I promise unnie"
