In his previous life, he was "White Fang", the top killer in the underground world, with his hands covered in blood. However, he was betrayed by his loved ones during an assassination mission and died in a well-planned explosion. Reborn at the age of sixteen, he became the cowardly and incompetent illegitimate son of the Cao family, a little puppy who could only hide in the corner and tremble. He was bullied wantonly by his stepmother and half-brother, and was even used as a bargaining chip to be sold to gangsters.
Only he knew that under this soft and harmless skin lived a lone wolf that could bite the enemy's throat at any time.
He originally thought that he would only live for revenge - the "mistress" woman who betrayed him was actually reborn as his stepmother. However, when the woman who kept asking him to die was the first to rush out to protect him during a family crisis, he discovered that the "mistress" in this world seemed completely different from the one in his memory. Serial killers, overseas mercenaries, hidden wealthy families... Many murderous intentions follow one after another. He must sharpen his fangs in dire straits and use killer methods to protect the only woman who is willing to stand in front of him in desperate situations - even if she is the enemy he hated in his previous life.
When the truth is torn apart layer by layer, is it hatred? Yes? Is it a fateful reincarnation or a bigger chess game? Whose "sacrifice" is it that he wants to protect?
