Two empires, both similar in prestige

In the fair city of Seoul, where we lay our scene

An old grudge healed by new matrimony

Where two are hand in hand

Do with marriage bound by their parents

A pair of crazy, psychotic, stubborn killers

Born by rivalry

Fall in love

Lips the color of ripened cherries, skin soft and sun-kissed to perfection, and brown eyes shimmering like that of an angel. Kim Haera may look the part, but she’s definitely nothing close to an angel. Bred to have the hands of a killer and be the next heir of the Kim Empire, she stops at nothing to get what she wants. That is, until she meets the equally ruthless Kai, who is next in line to rule the Exo Clan. Feared by many and trained to be an emotionless, heartless killing machine, Kai rules with an iron fist. Both leaders, although unwilling, have to surrender their power. . . . . . to each other?

One rivalry, two killers, and two hearts.

Blood may shed, tears may drip, love may form,

and the end may come.
