Gu Huaian–Gu Jinan brotherhood

Gu Huaian–Gu Jinan brotherhood is one of the book’s most important examples of kinship transformed into rivalry. The two men are brothers within the Gu family, yet their relationship is structured by suspicion, manipulation, and retaliation rather than trust. Gu Jinan presents himself through seemingly harmless incidents and insinuations, while Gu Huaian responds in ways that remain largely hidden from outsiders. Shen Tang’s presence exposes the emotional cost of this long conflict and makes the brothers’ private history part of the wider struggle surrounding the Gu family.

Family Bond and First Encounters

Gu Jinan enters the relationship as a figure whose polished appearance conceals threat. When he suddenly appears beside Shen Tang during a dispute over a third female-lead role, he asks what is happening and looks at her with apparently smiling almond-shaped eyes. The gesture is outwardly civil, but Shen Tang immediately experiences a physical reaction of unease, sensing that his intervention carries something more than simple concern. His manner establishes the central ambiguity of his relationship with Gu Huaian: he can occupy the position of a family member or mediator while simultaneously making the surrounding situation more dangerous.

Gu Huaian, by contrast, is shown as someone whose authority and physical ability exceed Shen Tang’s expectations. When he takes hold of her wrist, the sensation is warm and notably different from Gu Jinan’s grip, which she instinctively resists. The contrast is bodily before it becomes interpretive: Shen Tang distinguishes the brothers through the force and emotional meaning of their touch. Gu Huaian’s intervention therefore does not merely interrupt a confrontation; it marks a line between the brother who makes her feel threatened and the brother whose presence she is more willing to accept.

Childhood Pattern of Accusation

The decisive explanation for the brothers’ antagonism comes when Shen Tang asks Tao Sister what happened the previous night and learns that Gu Jinan had often bullied and framed Gu Huaian when they were children. His methods were deliberately indirect. He would pretend to fall and falsely accuse Gu Huaian of pushing him; he would break something and then claim that Gu Huaian had caused the damage. These incidents converted ordinary childhood mishaps into staged evidence, forcing Gu Huaian to defend himself against stories designed to sound plausible before adults.

The pattern matters because it reveals that Gu Jinan’s hostility is not a recent reaction to Shen Tang or to adult competition. It is an established strategy built around controlling appearances. Rather than confronting Gu Huaian openly, he makes himself appear injured or wronged and places his brother in the role of aggressor. The same logic later governs the brothers’ adult relationship: Gu Jinan’s power lies in creating suspicion, while Gu Huaian’s answer lies in countering him without exposing the full mechanism of the retaliation.

Retaliation Without Proof

Shen Tang’s anger after hearing this history changes her conduct. Whenever Gu Jinan’s name is mentioned, her blood rises and she feels an urge to hit someone. She stops visiting him in the hospital, even for the sake of appearances, because maintaining a public performance of concern would feel like cooperation with someone who had repeatedly harmed Gu Huaian. Her withdrawal is therefore not a neutral choice; it is an act of alignment with Gu Huaian and a refusal to preserve the polite surface of Gu-family relations.

The irony is that Gu Jinan is not free to act without consequence. After each frame-up, Gu Huaian secretly retaliates. Gu Jinan knows that Gu Huaian is responsible, but he cannot produce evidence and must endure the consequences in silence. The brothers’ conflict thus becomes a closed system of provocation and concealed punishment. Gu Jinan creates accusations that are difficult to disprove, and Gu Huaian answers with reprisals that are difficult to prove. Neither brother resolves the underlying hostility; each instead reinforces the other’s preferred method of indirect combat.

Shen Tang’s sympathy remains firmly with Gu Huaian even though she does not know every detail of his retaliation. The narrative presents the reprisals as a response to the person who began the cycle, while also emphasizing their secrecy and moral ambiguity. Gu Huaian is not simply passive or defenseless, and Gu Jinan is not merely an unpleasant sibling; both are participants in a long-running contest whose rules were established during childhood and preserved into adulthood.

Rivalry in the Wider Gu Family

The brothers’ relationship affects the conduct of people around them because the Gu family’s public order depends on appearances. Formal occasions require courtesy, introductions, and controlled behavior. At a high-status banquet, Shen Tang enters arm in arm with Gu Huaian and attracts attention before he introduces her as his wife to two kindly elders. The scene places Gu Huaian and Shen Tang together in the family’s public front stage, where unity and affection must be displayed even when private relationships are unstable.

Against this backdrop, Gu Jinan’s manipulative habits become especially consequential. The Gu name can be used to gain access, obtain advantages, or make other people believe that a request carries family authority. Shen Tang even considers whether someone has been using the Gu family’s name to show off and notes that Gu Wuyang’s name was invoked. Such incidents demonstrate why the brothers’ struggle cannot remain purely private: in a powerful family, identity itself is a resource, and a false accusation or borrowed name can alter how outsiders behave.

The rivalry also exists beside Gu Huaian’s other relationships and responsibilities. He attends to meals, files, work, and family appearances, while Shen Tang observes how easily his obligations interrupt ordinary domestic moments. Gu Jinan’s conflict with him is therefore not an isolated feud but one pressure within a larger network of family, business, reputation, and marriage. Every public display of harmony carries the possibility that hidden competition is continuing behind it.

Narrative Function and Development

Gu Huaian–Gu Jinan brotherhood gives the Gu-family plot a recurring structure of surface civility and buried antagonism. Gu Jinan’s smiling intervention, childhood false accusations, and later use of indirect framing all belong to the same pattern: he seeks advantage by making others interpret events in his favor. Gu Huaian’s secret retaliation supplies the counter-pattern, preserving his ability to answer Gu Jinan while denying the latter a clear case against him.

For Shen Tang, learning the brothers’ history is a turning point in perception. Before the revelation, she can still treat Gu Jinan as someone who must be handled for appearances. Afterward, his presence carries the accumulated force of years of deceit, and she no longer wishes to participate in even a symbolic relationship with him. The brotherhood consequently becomes a test of loyalty and judgment: Shen Tang must decide whether family etiquette deserves respect when it protects the person who first weaponized it.

The relationship’s significance lies in its refusal to present blood ties as automatic intimacy. Gu Huaian and Gu Jinan remain connected by family, but that connection provides the arena, vocabulary, and social cover for their conflict. Their history shows how repeated accusations can harden into identity, how retaliation can become a private language, and how a family’s demand for outward harmony may conceal a struggle that neither brother is prepared to end.
