Mo Beichen—Su Xiangcheng

Mo Beichen—Su Xiangcheng is a relationship shaped less by mutual romance than by unilateral pursuit, entitlement, and the unresolved obligation created when Su Xiangcheng saved Mo Beichen. Mo Beichen openly admits that he likes her and intends to keep pursuing her even without her consent, while Mo Beiyu repeatedly insists that the debt of being rescued requires him to treat her seriously rather than behave like a tyrant. The relationship therefore turns gratitude into a contested form of emotional leverage and places Su Xiangcheng’s freedom against Mo Beichen’s persistence.

Origin in Rescue and Obligation

Su Xiangcheng’s connection to Mo Beichen begins with an act of rescue. Mo Beiyu explains that she saved him when he was pretending to be Mo Beiyu, an encounter that made her the Mo family’s benefactor. Su Xiangcheng later says that she would have saved anyone in the same situation, but that Mo Beichen’s subsequent conduct made the memory difficult to reconcile with the injured, humble, and courteous man she had first encountered. In her eyes, his wounded vulnerability and his later arrogance appear to belong to entirely different people.

That contrast gives the relationship its central irony. The person Mo Beichen wants is also the person to whom he owes a serious debt, yet his pursuit does not become more respectful because of that debt. Mo Beiyu argues that, had Mo Beichen not acted independently, he might already have been accepted into the Mo Clan, and he condemns him for failing to follow the rules governing treatment of a benefactor. The supposed foundation for loyalty thus becomes evidence against Mo Beichen: the more important Su Xiangcheng’s saving him is, the less defensible his disregard for her wishes becomes.

Mo Beichen’s Pursuit

Mo Beichen describes his attachment in uncompromising terms. He tells a hoodlum over the phone that he likes Su Xiangcheng and will fall for her sooner or later even if he cannot obtain her heart. The statement treats her feelings as an obstacle to be outlasted rather than a condition that determines whether a relationship should exist. His language makes the pursuit itself a project, one whose success is imagined as inevitable regardless of her response.

Mo Beiyu recognizes the danger of this attitude and warns his brother that he may lose his only chance of ever having Su Xiangcheng, including physical intimacy with her. Mo Beichen’s silence after the warning suggests that the challenge reaches the point where his confidence fails, but it does not produce a demonstrated change in conduct. When he asks whether Mo Beiyu intends to compete with him for her, he converts an ethical reprimand into a rivalry between men. Su Xiangcheng’s position disappears from the frame, replaced by a contest over who may claim her.

The relationship consequently follows a pursuit pattern rather than a reciprocal romantic progression. Mo Beichen’s repeated insistence, his refusal to accept emotional rejection as final, and his readiness to frame resistance as part of the chase all support the description of the bond as coercive. The pursuit is not presented as a negotiated courtship; it is an attempt to wear down opposition through persistence.

Family Conflict and Moral Condemnation

The relationship also exposes a fracture within the Mo family. Mo Beiyu acts as both brother and moral accuser, defending Su Xiangcheng’s status as the family’s benefactor while rebuking Mo Beichen for the way he treats her. His anger culminates in a direct condemnation of Mo Beichen’s conduct: instead of honoring the woman who saved him, Mo Beichen behaves as though affection grants him permission to disregard her boundaries.

Mo Beiyu’s intervention establishes an internal standard that Mo Beichen fails to meet. Gratitude, family rules, and romantic desire are placed in direct conflict. Mo Beichen wants to transform the rescue into an emotional bond on his own terms; Mo Beiyu insists that the rescue creates a responsibility to take Su Xiangcheng seriously. The brothers therefore disagree not simply about the same woman, but about whether desire can override obligation and consent.

The wider narrative reinforces this moral framework through Mo Beiyu’s confrontation with Lu Xun. After seeing Su Xiangcheng in a severely weakened state, Mo Beiyu condemns the man responsible for abusing her and argues that someone who has tortured his woman has no moral qualification to stand openly before others. Although this confrontation is not itself a direct exchange between Mo Beichen and Su Xiangcheng, it clarifies the protective principle Mo Beiyu applies to the people he considers vulnerable: possession does not excuse violence, and a claim of intimacy does not erase the need for accountability.

Boundaries, Kinship, and Rival Desire

The relationship is repeatedly surrounded by unstable kinship language. Shen Yiyun is described as Lu Xun’s cousin through adoption rather than blood, and Su Xiangcheng challenges the use of such family terminology when it conceals a man-woman relationship. She argues that a relative connected only by name remains a potential romantic boundary rather than an automatically protected familial one. This debate gives the Mo Beichen–Su Xiangcheng pursuit a broader context: the story repeatedly tests whether labels such as cousin, sibling, wife, or benefactor clarify intimacy or merely provide cover for competing claims.

Chu Fei’s rivalry with Lu Xun makes the same instability explicit in another form. Chu Fei says that a woman who had once appeared to be a close relative was not actually related to him and that he liked her deeply; he then describes pursuit as more appealing than immediate possession. His declaration does not establish a separate relationship with Su Xiangcheng in this passage, but it mirrors the narrative logic surrounding Mo Beichen: desire is dramatized through the chase, while supposed kinship becomes a boundary to challenge rather than a reason to withdraw.

Su Xiangcheng’s own married identity provides the clearest counterweight to these competing claims. When Lu Xun asks what their relationship is, she identifies him as her husband, even while her intoxication leaves him uncertain whether she fully recognizes him. That moment places her in an existing marital bond and sharply limits the legitimacy of Mo Beichen’s pursuit. Her declaration does not turn the Mo Beichen relationship into a triangle of equal claims; it demonstrates that Mo Beichen’s desire conflicts with a status Su Xiangcheng herself publicly names.

Narrative Significance

Mo Beichen—Su Xiangcheng functions as a study in the difference between rescue, gratitude, and love. Su Xiangcheng’s act is unconditional: she says she would have saved anyone. Mo Beichen’s response is conditional and possessive: he treats her singular importance to him as grounds for continuing to pursue her even when her heart is unavailable. The asymmetry is decisive. A generous act becomes the origin of an unwanted claim, while the pursued woman retains the moral clarity of having helped without bargaining for affection.

The relationship also supplies a counterpoint to more reciprocal forms of intimacy in the surrounding plot. Su Xiangcheng can name Lu Xun as her husband, but Mo Beichen can only announce his own intention to keep chasing her. His pursuit has intensity, yet the evidence gives it no corresponding consent, mutual commitment, or secure ending. Its narrative force lies precisely in that imbalance: the more insistently Mo Beichen declares that he will eventually win, the more clearly the relationship reveals the coercive structure beneath the language of romance.
