Two precessions, sibling love, the same mother, half-bred, no blood relationship, falling in love and killing each other, reverse narration, reminiscing. From campus to workplace, from urban fireworks to the underground black market and tropical rainforest. HE. The heroine is the risk control director of a large Internet company. She is a tough-talking and soft-hearted business manager VS the male protagonist is a dark web special soldier. She is an undercover agent who fights against transnational pornographic crimes. She and the heroine are very different in character. However, they can bow their heads and be submissive. They are paranoid, sinister and possessive.
The second man and the second woman are tool people.
