In the ABO world dominated by pheromones, S-class Alpha Xie Yanci never thought that his fate would be changed by an unexpected reverse mark - the one who marked him was actually Enigma Ji Xingran who had hidden his identity. From the initial hatred and resistance to fighting side by side, the pheromones of ebony and cedar fragrant intertwined in the crisis. The two worked together to destroy the illegal pheromone laboratory, confront the conspiracy of the careerist Wei Mingyuan, and broke the taboo of the love between Enigma and Alpha.
At the same time, the cold-hearted S-class Alpha Lu Jin and the gentle and tough Omega Su Nianxing gradually fell in love with each other during missions. The peach-flavored and liquor-flavored pheromones healed each other, performing the two-way rush of traditional AO. Two pairs of lovers, a forbidden love that transcends the rules, and a gentle rush to protect each other. They use love as a blade to pierce prejudice and conspiracy. In the turbulent situation of the Federation, they jointly write a passionate and romantic story of walking side by side and remaining unswerving until death.
