It must be nice to be a goldfish. They don't seem to mind that their tanks are so smal and restrictive, or that they have no direction, swimming from one end of the tank to the other. Hyojung watches them weave through the green plastic leaves and she grimaces. 

Everything seems so clustered in there and there are so many of them in one tank... Hyojung feels the all too familiar itch in her body, the discomfort and agitation. She remembers at her old home when Leopold had a larger tank. She had tried to make it as unclusttered as possible but Chanyeol - her step brother - insisted on putting stalks of bamboo in there because let's face it, the life of a fish is a very boring one. 

Sometimes Hyojung disagrees. She wouldn't mind having a memory that only lasts seconds. She could forget that she's stuck in a tank but she would still be there. Hyojung grimaces, her nails digging into the palm of her skin.

Perhaps it wouldn't be so nice. The constant panic attacks repeating over and over again would drive her insane.

Meet Hyojung, the agoraphobic and claustrophobic fiancee of Lu Han. Of course he didn't pick her to marry; his parents did. As the daughter of the CEO and owner of Park Enterprises, Hyojung is somewhat obligated to expand the business, even if it means destroying her comfort zone.

Meet Lu Han, the handsom and charming fiance of Park Hyojung. Of course she didn't agree to marry him; her parents did. As the future heir of Crown Royal, it is a given that he must help improve the expanding empire, even if it means giving up a future with the love of his life.

The two are just small fish in a big tank, but they're about to find out that there's a lot more past the glass that cages them.
