Biodata

Power Progression

Appearance

• Hair: Waist-length 141.
• Features: Described as having exquisite, charming features and a curvaceous figure 94 95.
• Apparent age: Looks seventeen or eighteen when Cao Yu reunites with her in Xuan Ziwen’s classroom 141.
• Relative height: At their reunion, she reaches only Cao Yu’s chin even when standing on tiptoe, despite remembering that they were once the same height 142.

Personality

Ju Zi is playful and adept at turning an awkward situation to her advantage. After Cao Yu returns to the academy, she threatens to expose his earlier intrusion until he calls her “Big Sister.” Her confidence does not prevent her from becoming embarrassed when the cafeteria staff tease her about their relationship 142.

She is normally meticulous and highly efficient in her experiments, according to Xuan Ziwen. Cao Yu’s unexpected return distracts her enough that her teacher repeatedly reminds her to concentrate 141.

Her affection is accompanied by jealousy. She competes with Meng Hongchen for Cao Yu’s attention, serves him extra-spicy skewers after learning they are dating, and later plans a chili-powder prank because their public affection upsets her 144 166 174. Nevertheless, she is considerate of Ke Ke’s feelings and initially hides her own relationship with Cao Yu out of fear of hurting their friendship 175.

Ju Zi takes pride in her cooking without treating herself as beyond improvement. At the Linhai Grand Hotel, she openly admires the chef’s grilled meat and sauce and acknowledges that she still has more to learn 172.

History

Early Life and First Encounter

Ju Zi’s parents died in war. Xu Tianran had previously shown her kindness and groomed her as a trusted aide, making her eventual departure with Shrek’s exchange students difficult for him to accept 221 262.

Cao Yu first observes Ju Zi and Ke Ke working in an academy laboratory while he is secretly exploring the Sun Moon Imperial Soul Engineering Academy. Later that night, he enters Ju Zi’s room while fleeing the alarm raised by his thefts. She confronts him but denies seeing an intruder when a searcher comes to her door 94 95.

Before escaping, Cao Yu gives her a necklace and promises that they will meet again. Ju Zi doubts the promise but puts the necklace away 95 96.

Reunion Under Xuan Ziwen

Years later, Ju Zi discovers that Cao Yu has returned openly as a Shrek exchange student assigned to Xuan Ziwen. Her astonishment and repeated glances at him lead her teacher to mistake her reaction for love at first sight 141.

She uses their shared secret to make Cao Yu call her “Big Sister,” establishing their playful sworn-sibling relationship. Her attraction soon brings her into competition with Meng Hongchen, particularly during a cafeteria meal where both girls keep adding meat to his bowl 142 144.

Jingyang Mountain Range Expedition

Ju Zi joins Cao Yu, Ke Ke, Zi Mu, and Wang Shaojie to test Xuan Ziwen’s All-Terrain Detection Soul Tool. She demonstrates the prototype and helps prepare the group’s meals. When five Earth-Splitting Bears approach their camp, she and Ke Ke provide ranged support while the three men hold the front line 147 148.

The group returns safely, and Ju Zi delivers the test data to Xuan Ziwen. At their celebratory dinner, Cao Yu again suggests having her cook for him for life, prompting Xuan Ziwen to encourage him to be bolder 149.

Relationship with Cao Yu

During the Linhai Beach trip, Ju Zi learns that Cao Yu and Meng Hongchen have begun dating and admits to Ke Ke that she likes him too. Her jealousy eventually leads her to enter his room intending to prank him with chili powder 166 172 174.

Cao Yu mistakes her for Meng Hongchen in the dark, and they have a sexual encounter. Afterward, Ju Zi expresses hurt over losing her first time and initially asks him to forget the incident. He apologizes, promises to take responsibility, and reveals that he has other fiancées. The two reconcile and begin an acknowledged romantic relationship 174 175.

Ju Zi later accompanies Cao Yu to Shrek Academy. At the Sea God Lake Matchmaking Convention, she explains that they shared a mentor for three years and that she followed him after he offered to hire her as his lifelong chef 188 202.

Marriage and Motherhood

Ju Zi marries Cao Yu in his shared wedding ceremony, completing the wedding bows with him before their guests. Zi Mu attends despite his lingering feelings for her 262.

Several months after the wedding, Cao Yu’s thirteen wives show signs of pregnancy. Ju Zi later gives birth to one of the family’s thirteen children; her child’s name and gender are not specified in the provided account 268 282.

Relationships

• Cao Yu — Husband and fellow student of Xuan Ziwen. Their relationship develops from a concealed encounter and teasing sworn-sibling arrangement into romance, marriage, and parenthood 95 142 174 262 282.
• Ke Ke — Close friend and laboratory partner. Ke Ke initially encourages her to consider a senior’s romantic interest; Ju Zi later worries that revealing her relationship with Cao Yu will hurt Ke Ke, who also likes him 94 175.
• Xuan Ziwen — Teacher. Values her efficiency, entrusts her with experimental work and field-test reporting, and encourages Cao Yu to be more direct about his feelings for her 141 142 149.
• Meng Hongchen — Initially a romantic rival. After Cao Yu explains his relationship with Ju Zi, the two become comfortable sharing affectionate time with him 144 194.
• Zi Mu — Classmate with unrequited feelings for her. He views Cao Yu as his principal rival and remains affected when he witnesses their wedding 147 184 262.
• Xu Tianran — Former benefactor who cultivated her as a trusted aide. Her departure with the Shrek group ends those plans 221.
• Bai Xiuxiu — Junior classmate whose interest in Cao Yu draws Ju Zi’s suspicion. Ju Zi persuades Cao Yu to have Xiuxiu sit with Ke Ke rather than beside him 183 184.
