Dara was adopted into one of South Korea's most dangerous and wealthiest mob, the White Snake when she was still three years old.

She was used for one sole purpose, to be an assassin with no records of existence. The cold assassin was then given another mission by the White Snake's head: to kill the Black Dragon's apparent heir.

in order to observe his next prey, she needs to get close, even enrolling in his school.

Will she still be able to accomplish her  mission once she starts to warm up to the people now surrounding her???
