In the shadows of Seoul, the Kim brothers rule as kings of the underground - ruthless, feared, and untouchable. Guns, blood, and power are all they've ever known.
But everything changes the day their father marries his secretary... and brings home a new stepsister.
Seven-year-old Yoo Ahri is nothing like their world. She's pure light in a house built of darkness - shy smile, chubby cheeks, and eyes that see no evil. The brothers don't know whether to protect her... or push her away before the darkness swallows her whole.
What they don't realize is that even the smallest butterfly can stir a storm.
And in a family where trust can kill, an innocent heart may be the most dangerous thing of all.
