Chloe Sterling is the last daughter of the ancient Sterling vampire bloodline, a noble family that rules from a secluded castle hidden deep within the mountains. Despite her cold and regal appearance, Chloe once spent her childhood with a close friend who was the only person able to see her gentle side. Many years ago, that friend left for another country, and the two gradually lost contact as time passed.

In the present day, Chloe has returned to her family’s throne room as a graceful and mysterious vampire noblewoman. To strengthen the Sterling bloodline and secure the future of their house, her parents decided to arrange her marriage—especially her father, Leon Sterling, the strict and influential head of the Sterling family. The person chosen is the very same childhood friend she has not seen in a very long time, forcing both of them to reunite after years of distance, change, and unspoken feelings.
