Xi Luhan was Satan.

Kim Jongin was Lucifer.

Im Yoona was the answer. 

All they wanted was to be loved. But it wasn't simple. One was a wicked devil, the other was a fallen angel and she was heart broken. Entangled in lies in this ruthless world lust, hatred and jealously emerge. Could all this lead to a happy ending or a greater tragedy than Romeo and Juliet?

Xi Luhan - the oldest heir of the G.H enterprise. He was always cold, insolent and arrogant. Originally from China, he decided to move to South Korea to search for the "Great Perhaps". 

Kim Jongin - Vice director of Marcel and Briel investment group. He used to be kind and gentle once. But once he realized he could not survive in this corrupt society he changed. He spent the last 20 years aboard in France but surpisingly returned to South Korea to find "inspiration".

Im Yoona - an aspiring prima ballerina and heiress of J.Y. Fashion. She was once a strong, dignified lady. But one twist broke her heart into a million fragments. How will she ever get out of this labyrinth?

Have you ever been in love? Horrible isn't it? It makes you so vulnerable. - Neil Gaiman
