Shen Xingchen, a senior girl, went to the border of Yunnan to do some research and accidentally photographed a secret stronghold of a drug cartel. She was targeted on her way back to school, and at a critical moment she snatched an unmanned tricycle - the owner of the car, Xie Qingshan, was a plainclothes anti-narcotics policeman who fell in love with her at first sight without knowing it.
He left her contact information and said "it's needed for the mission", but he repeatedly clicked on her profile picture every night.
She sensed that she was being followed and threatened, and her mother was also involved. He rushed to protect her, but had to confess: the boss behind the criminal group who was chasing her was his biological father whom he had not seen for thirty years.
"Shen Xingchen, I have wanted to catch him myself since I was three years old. But he has set his sights on you."
She wiped away her tears and said, "Then you teach me. I'll join you."
From then on, she delivered information for him, acted as a bait, and was even kidnapped to Myanmar, where she carved an escape map on the wall with her fingernails. He chased him from the border to the city, crawled back from hell, and finally confronted his father at gunpoint——
"It is precisely because of your blood that I want to end this with my own hands."
This is a story about love growing in the soil of hate. A drug police officer falls in love with the daughter of the man he wants to arrest. The son of a drug lord spends his life proving that he is different from his father. And she was his only light in all the darkness.
