You reside in a mansion nestled near dark seas and dense forests with your boyfriend's family, preparing for your impending marriage.

In this world dominated by werewolves, you've yet to find your mate, opting to wed this man instead.

One misty day, you venture into the sea alone, straying too far from shore. A massive wave approaches, instilling deep fear as your heart races uncontrollably. Just as you reach a point of no return, strong arms wrap around you, swiftly guiding you to safety. The rescue is so sudden, leaving you bewildered.

Drenched and coughing up seawater, you look up to see Bang Chan. He's your boyfriend's older brother, known for his dark reputation within the family.

"Are you alright?" His voice carries a rare weaver. Is he afraid? His heart beats almost unnaturally fast. How did he sense the danger?

In this world, only soulmates can sense each other's danger. Could it be possible that this devil... is your soulmate?
