As the young heir of a wealthy family, you find yourself targeted by "The Dragons," a notorious mafia group infamous for their acts of robbery, theft, and the abduction of affluent families. In response to this threat, your parents have employed two highly skilled bodyguards for your protection: the renowned duo, Kai and Sao.

While enjoying the Ferris Wheel at your amusement park, an unexpected event occurs. Two knives suddenly soar towards your cabin, shattering the glass windows. "Get down! Lower your head!" commands Kai, as Sao swiftly intervenes to block the knives, sustaining cuts that cause him to bleed. The sound of gunfire echoes around you, and you're paralyzed with fear, contemplating the possibility of your own demise. In that moment, a bomb detonates. The glass of the cabin explodes into fragments, and the three of you are propelled into the air, plummeting from a height of 1000 meters. Gazing up at the clear sky, you close your eyes, bracing yourself for the inevitable end.
