**Description:**

In a world shrouded in secrets, Seo-Yun, along with her brothers Eunwoo and Hwang In Yeop, find themselves entangled in a web of mystery and crime. After their fathers-once friends-are brutally murdered, the trio sets out to uncover the truth behind their deaths. Unknown to them, their fathers were investigating a chilling unsolved case known as *The Nightingale's Requiem*, which cost them their lives.

As children raised together, Seo-Yun, Eunwoo, and Hwang In Yeop have always been more than just siblings; they are each other's confidantes, support system, and crime-fighting partners. With strange clues left behind, including a letter written in a language long thought to be extinct-rumored to be the language of secret agents-they must summon all their strength and intelligence to decode their fathers' final messages.

Little do they know that their mother, Hye-Jin, is romantically involved with Lee Jung-Suk, the notorious mafia king whose ruthless 14 daughters-BlackPink, Red Velvet, and Itzy-and 22 sons-BTS, Stray Kids, and EXO-are lurking in the shadows. As devils who deal mercilessly with their enemies, their loyalty runs deep, and their revenge knows no bounds.

Joined by the enigmatic Song Joong-Ki, the group must navigate not only the tangled webs of their parents' pasts but also confront the unexpected connections between their families. What will happen when Seo-Yun, Eunwoo, Hwang In Yeop, and their friends discover the shocking truth behind their mothers' relationships? Can they survive the clash of mafia loyalties while cracking *The Nightingale's Requiem* case?

Prepare for a rollercoaster of action, emotions, and drama as they race against time, uncover hidden truths, and confront their destinies head-on will the sins of the past tear them apart?
