The protagonist, who is in charge of the situation in the dark, kills calmly throughout his life, but he loses to a life-long regret. The person he cherished died before his eyes, and his indolence caused him to trap himself, trapped in endless self-accusation and isolation.
In order to pull him out of his ruin, the only brother who protected him when he grew up took him back to his country and traced his origins to find his relatives. Returning to his native family, he found himself in a seemingly warm bond of flesh and blood, but he had already seen layers of lies and a deliberately concealed past.
He did not expose the scam, but chose to follow the trend, love and hate in the intertwined family relationship between true and false, and repay the blood debt he was born with bit by bit. With unresolved debts, accumulated pain, and all kinds of shackles, he is determined to end all entanglements and force out the entire truth that has been sealed for many years.
Purpose: Cowardice is never an excuse for compromise. Bravery is the only way out. There are many choices in the world, but it just depends on the choice of the human heart whether to sink or move forward.
