The boy and the wind who met for the first time in the heavy rain had a bond that spanned life and death.
Lu Yuchen is the "perfect boy" who ranks first in grade, and Xu Han is the "hyacinth boy" who is partial to subjects. The formulas and notes in the cram school, the burdens and heartbeats at the sports meeting have allowed the two teenagers to plant the purest love in their youth. The admission notice from the Anti-Narcotics Department of the police academy melted their ideals into the same passion - until Lu Yuchen disappeared for an undercover mission, and Xu Han went through mountains and ridges while losing contact, he discovered that the so-called "mission failure" was actually a carefully planned life and death situation.
The blue butterfly is the ghost of the new drug, and the hyacinth is the token of transcending darkness. When Lu Yuchen wore half a brooch to disguise himself in the drug lord's lair, and when Xu Han wrote "Shen Yan" in blood at the drug dealer's gunpoint, they finally understood: the most dangerous undercover conceals the brightest heartbeat; the most painful separation is for the most eternal reunion.
This is the growth epic of two teenagers, the bloody romance of the drug police, and the life and death fable of Hyacinth and Blue Butterfly - love and justice will eventually bloom the toughest flowers in the darkness.
Concept: Growth of two male protagonists, anti-drug criminal investigation, suspenseful adventure and youth bonding
