The heroine returned to China and became a lecturer in the Department of Architecture at her alma mater. During the renovation project of the school history museum, she reunited with the hero, the current dean of the Institute of Biotechnology. Because her father's engineering collapse indirectly killed the male protagonist's parents, the female protagonist is full of guilt and dare not face the passionate and affectionate love of the male protagonist.
Later, the male protagonist discovers that a similar causative archaea has lurked in the female protagonist's body and is genetically specific. Only the specific genes he carries can induce lethal mutations in the flora. In order to develop antibodies, he collected data through close contact and took the initiative to conduct high-concentration live exposure to test antibodies. He suffered alone in the dilemma of "cannot touch her to save her life" and "desire to touch the person who loves her".
Until the male protagonist was unfortunately infected due to high-concentration testing of the drug, in order to protect the female protagonist, he began to deliberately neglect her. After the heroine discovered the truth, she completely broke through her defenses and used her professional knowledge of ancient architecture to help the hero extract the original strain.
In the end, the two teamed up to use genetic technology to eradicate the deadly flora, uncover the truth about the accident and untie their knots, achieve self-reconciliation, and reunite with each other.
Purpose: to interpret the restraint and sacrifice of love in the test of life and death, and to achieve two-way redemption and self-reconciliation.
