Gu Nanfeng is a high-ranking Sentinel in the Federation's Third Legion, known for his exceptional combat skills, charismatic personality, and foul mouth. His spirit animal is a cougar, and he excels in solo missions and ambushes. Despite his popularity among guides, he maintains a dismissive attitude toward others. Qiao Si Yu is a mute guide with immense mental strength who is deployed to the frontlines due to mission requirements. Their first encounter is hostile; after Gu Nanfeng flirts with Si Yu, the guide uses his mental powers to slap Gu Nanfeng dozens of times in the mind, leaving a lasting grudge. Gu Nanfeng resents Si Yu's perceived pettiness, while Si Yu is frustrated by the constant hype surrounding Gu Nanfeng's reputation.
When assigned to the same special operations squad, their initial conflict continues. Gu Nanfeng underestimates Si Yu, expecting a fragile support role, but discovers that the guide is also a capable fighter who can defend himself and protect the team's mental barriers. During a mission ambush, Si Yu is injured and his mental state becomes unstable, causing his pheromones to leak. Gu Nanfeng, affected by the pheromones, struggles with overwhelming desire but prioritizes Si Yu's safety, carrying him to safety. In the process, Si Yu accidentally establishes a temporary mental bond with Gu Nanfeng by kissing him to stabilize his condition. This bond enhances their combat synchronization significantly, allowing them to defeat enemies with perfect coordination. However, the temporary nature of the bond and Gu Nanfeng's continued rude behavior lead to tension.
After the mission, Gu Nanfeng is offered a position in the Marshal's independent regiment, the unit of his idol. He accepts eagerly, unaware that Si Yu is the Marshal's chief guide and had specifically requested to be paired with him. A superior reveals that Si Yu came to the frontlines specifically for Gu Nanfeng and that they have an 80% compatibility match arranged six years prior by Gu Nanfeng's family. Gu Nanfeng had run away from home at that time to pursue his military dreams, never knowing the identity of his matched guide. Realizing Si Yu is the person his family had chosen, Gu Nanfeng is shocked and distressed.
Si Yu, meanwhile, has spent six years following Gu Nanfeng's career and keeping detailed records of him. He had hoped that becoming a high-level guide would make Gu Nanfeng accept him. However, Gu Nanfeng's initial rejection and rude comments hurt Si Yu deeply. He burns his notebooks containing his observations of Gu Nanfeng, believing his feelings were unrequited. When Gu Nanfeng finally tracks Si Yu down to apologize, explaining that he did not recognize him and regrets his past behavior, Si Yu remains distant. Gu Nanfeng, desperate to make amends, begins courting Si Yu by bringing him fruit and spending time with him. He learns to communicate carefully, trying to overcome his past mistakes.
The turning point occurs when Gu Nanfeng and Si Yu are in the simulation room. Si Yu, misinterpreting Gu Nanfeng's hesitation as rejection, offers to cancel their match. Gu Nanfeng, panicked, kisses him to stop him. They eventually form a permanent mental bond. Gu Nanfeng, feeling unworthy of Si Yu's dedication, asks him to wait half a year while he strives to reach the top of his regiment. During this time, Si Yu's bat accidentally reveals Si Yu's notebooks to Gu Nanfeng, showing the depth of his devotion. Gu Nanfeng is moved and realizes his own shortcomings.
Gu Nanfeng takes Si Yu to meet his family and proposes, promising to be his voice and family for the rest of their lives. He explains that he wanted to achieve greatness to be worthy of Si Yu. Si Yu, touched by Gu Nanfeng's sincerity and growth, accepts. The story concludes with the two formally bonded partners, ready to face the future together, having overcome their initial hostility and misunderstandings through mutual respect and love.
