The arrival of Nurul Iman, Zaim's first wife, creates fresh turmoil as Syafiqah and Che Yam refuse to accept her presence. Zaim struggles to balance his relationships with both wives and his mother. Meanwhile, Hadith and Husna's honeymoon is cancelled after their travel plans are disrupted by a damaged passport. Husna attempts to concentrate on her fashion-design business, but Che Yam continues sabotaging her work.

Che Yam openly admits her hatred of Husna, revealing the malicious intentions behind several incidents that have plagued the young marriage. Her manipulations include the wedding bracelet, damaged fashion designs and Hadith's destroyed passport. As Husna begins understanding the extent of her mother-in-law's hostility, she becomes emotionally overwhelmed. The confrontation exposes the depth of Che Yam's resentment and threatens the family's already fragile relationships.

Husna and Luth are left outside Che Yam's home in heavy rain until Hadith returns and rescues them. Disturbed by his mother's cruelty, Hadith struggles with guilt over the suffering his wife and stepson endure. Che Yam continues creating difficulties for Husna, while Syafiqah manipulates Zaim and becomes involved with a traditional sorcerer to harm Haji Zakaria. The family's growing tensions reveal the increasingly dangerous methods being used against those who resist their schemes.

Che Yam intensifies her campaign against Husna by deliberately destroying clothing commissioned from her fashion business. Syafiqah secretly puts laxatives into food, allowing Che Yam to accuse Husna of poisoning the family. As the accusations become increasingly outrageous, Hadith intervenes to defend his wife against the mistreatment. His support only fuels Che Yam's anger, creating another confrontation within the household and making Husna's position even more difficult.

Family tensions escalate when Syafiqah attempts to harm Husna, prompting Hadith to protect his wife and stepson. Seeking safety and emotional relief, Husna returns to her hometown, where her mother and younger sibling warmly welcome her. Hadith continues visiting and supporting her despite the distance between them. Meanwhile, Farhana becomes increasingly determined to attract Hadith's attention, but he rejects her advances and remains faithful to Husna.

Hadith firmly distances himself from Farhana's persistent romantic advances and returns to the village to spend time with Husna. Their reunion allows them to reflect on their shared history and the affection that brought them together. Meanwhile, Che Yam's health begins deteriorating, adding another complication to the family's troubles. Syafiqah and Farhana continue conspiring to separate the couple, hoping to create an opportunity for Farhana to win Hadith.

Haji Zakaria's hospitalization leaves the family worried about his declining condition. Che Yam blames supernatural influences for his suffering, while Syafiqah secretly turns to occult rituals in an attempt to accelerate his death. Alma becomes increasingly distressed about Zakaria's health, and Syafiqah remains indifferent to his well-being. Throughout the crisis, Hadith supports Husna as she continues caring for his father despite the hostility surrounding her.

Hadith confronts Zaim and Che Yam over Zaim's unwillingness to care for his ailing father. Husna suspects Zaim's unusual behaviour may be connected to supernatural manipulation. Meanwhile, Farhana becomes more determined to marry Hadith, even if it means becoming his second wife, with Che Yam actively encouraging her ambitions. Iman also begins questioning Alma about her true relationship with Haji Zakaria, suggesting that a long-hidden family secret may soon emerge.

Zaim's behaviour becomes increasingly troubling when he pressures Iman to obtain a loan, creating serious problems in their marriage. Husna continues caring devotedly for her disabled father-in-law, while Hadith protects her from Farhana's continued attempts to interfere in their relationship. Alma also takes responsibility for helping Zakaria, with unresolved emotions surrounding her relationship with the family. Meanwhile, Syafiqah tightens her control over Zaim and pressures him to cooperate with her schemes.

Che Yam and Alma visit Husna's mother to persuade Husna to return to the family home. Although reluctant, Husna agrees after her mother urges her to reconcile with the family. Hadith becomes furious upon discovering that Che Yam pressured his wife into returning. Meanwhile, Syafiqah continues avoiding responsibility for caring for Haji Zakaria, forcing Zaim to remain at home. A series of disturbing incidents involving Iman leaves Zaim increasingly troubled by his actions and struggling with guilt.

Haji Zakaria's death devastates the family and exposes a shocking secret: Alma was his second wife. Che Yam reacts furiously to the discovery, feeling betrayed by her late husband's hidden marriage. As the family struggles with grief and the revelation, Hadith faces the complicated responsibility of managing his father's inheritance. Meanwhile, Syafiqah becomes increasingly anxious and dependent on her sorcerer, raising further concerns about the destructive influence of her supernatural practices.

The distribution of Haji Zakaria's estate creates bitter divisions when the appointed lawyer reveals that Alma and her child are entitled to part of his inheritance. Enraged by the revelation, Che Yam drives Alma away and also forces Husna out of the family home. Hadith witnesses the confrontation and continues defending his wife, further angering his mother. Meanwhile, Syafiqah strengthens her influence over Che Yam and Farhana, exploiting the family's financial and emotional turmoil for her own advantage.

Zaim and Iman's marriage reaches a breaking point as their disagreements intensify, leaving divorce appearing to be their only solution. Meanwhile, Syafiqah attempts to involve Farhana in her superstitious and occult practices, drawing another person into her dangerous schemes. Che Yam becomes increasingly aggressive toward Husna, determined to maintain control over the household. However, Husna begins showing greater confidence and refuses to remain silent when confronted with humiliation and injustice.

Che Yam attempts to arrange a marriage between Hadith and Farhana, publicly humiliating Husna in the process. Hadith reacts angrily and firmly defends his wife, refusing to accept his mother's interference. Farhana's mother also objects to the proposed arrangement, while Syafiqah delights in the resulting family conflict. Elsewhere, Zaim begins standing up against Syafiqah's controlling behaviour and expresses his desire to reconcile with Iman, signalling a possible change in his troubled personal life.

Husna's hospitalization causes widespread concern as the family confronts the seriousness of her condition. Farhana finally recognizes the harm she has caused and sincerely apologizes to Hadith and Husna for interfering in their marriage. Meanwhile, Che Yam remains determined to prevent Alma from receiving any share of her wealth, refusing to compromise despite the escalating inheritance dispute. Hadith confronts his mother after discovering the truth about Husna's illness, deepening the conflict between his responsibilities as a husband and a son.

Hadith makes a life-changing decision to leave his mother's home and begin a new life with Husna. Determined to establish their independence, he searches for employment while attempting to rebuild their relationship away from constant family interference. Che Yam becomes distressed when she realizes her beloved son is willing to distance himself from her. Meanwhile, Syafiqah celebrates what she believes is the success of her manipulations, while Zaim works to regain Iman's affection and repair their damaged marriage.

Syafiqah adopts a more affectionate attitude toward Che Yam, secretly hoping to earn her trust and gain control of the family plantation. Unaware of her true intentions, Che Yam considers transferring the valuable property to Syafiqah. At the same time, she angrily rejects visits from Hadith and Zaim, widening the distance between herself and her sons. However, Syafiqah's carefully constructed deception begins collapsing when Che Yam unexpectedly discovers her involvement in forbidden occult practices.

Hadith visits Che Yam and becomes alarmed by her increasingly frail condition, proposing that she move into his home so the family can care for her. After enduring years of mistreatment, Husna begins displaying a noticeably different attitude toward her mother-in-law, forcing Che Yam to reflect on her past cruelty. Meanwhile, Zaim finally divorces Syafiqah and considers reporting her activities to the police. Fearing the consequences of her actions, Syafiqah escapes before she can be confronted.

In the season finale, years of resentment erupt when Husna loses control of her emotions during a confrontation with Che Yam. Hadith witnesses the incident and angrily reprimands Husna for her treatment of his mother. Shortly afterward, Husna is involved in a devastating accident that leaves her legs paralyzed, creating another heartbreaking crisis for the family. Meanwhile, a desperate Syafiqah faces serious financial problems and begins plotting to kidnap Che Yam, threatening to plunge the already fractured family into further danger.
