An Yubei

Biodata

Background

Previous Life

An Yubei grew up without a family and struggled to support himself. At school, he had no close friends and avoided group activities because he lacked both money and companions. A childhood caregiver once beat him severely for getting up at night to use the bathroom, leaving him with a lasting association between mistakes and punishment 21 25 39.

He became a programmer, but competition from artificial intelligence eventually reduced him to working at a small company for three thousand yuan a month. Endless coding, bug fixes, and overtime damaged his health; he ultimately died suddenly from overwork 26 48.

Identity in the Novel

He transmigrates into the body of another An Yubei, the Ji family’s adopted son and Ji Shang’s fiancé. The original owner had staged a car accident to frame Ji Shang, followed Lu Jincheng, and acquired a reputation as an ambitious, incompetent troublemaker who coveted the Ji family fortune 1 4 7 8.

In the novel’s original course, An Yubei would be sent away to herd sheep, while Ji Shang would face bankruptcy. The transmigrated An Yubei instead wants to preserve his comfortable new life and the family affection he never had before 6 22.

Appearance

An Yubei has a youthful, delicate appearance and a soft, sweet voice. He is roughly half a head shorter than Ji Shang and is also shorter than Lu Jinsheng 5 9 10.

• Eyes: Almond-shaped, with long eyelashes 11 45.
• Smile: Often reveals a small, sharp canine tooth 5 12 76.
• Build: Fair-skinned, with a slender waist, delicate hands, and distinct lower-back dimples 5 10 33.
• Presentation: Successfully passes as a woman while wearing a skirt during an evidence-gathering operation, though he personally dislikes how he looks in it 95.

Personality

An Yubei prefers sleep, good food, entertainment, and financial security to professional ambition. His reluctance to work comes directly from having worked himself to death: he wants to enjoy his second life rather than repeat the first. Nevertheless, he distinguishes “lying flat” from becoming helpless and insists on doing things for himself when Ji Shang’s pampering becomes excessive 26 48 54.

His lack of family affection makes him unusually sensitive to rejection. Early on, he fears that causing trouble or behaving badly will make Ji Shang stop loving him. He treasures ordinary experiences—such as visiting an amusement park with family—because he previously watched others enjoy them from the outside 21 22 25.

He is socially anxious, cautious around unfamiliar people, and easily embarrassed by public attention. He also worries about others’ opinions of his relationship with Ji Shang. Zhao Fei recognizes that his tentative manner is unlike the superiority commonly expected of a wealthy young master 6 18 47 77.

Despite his timidity, An Yubei is loyal and willing to confront wrongdoing. He shields Lu Jinsheng despite having no fighting ability, challenges the police over Lu Jinsheng’s arrest, and refuses to forgive Wang Yu merely because he apologizes. His kindness does not mean he accepts that victims owe their attackers reconciliation 10 19 20 21.

He is initially inexperienced with romance and repeatedly mistakes flirtation for friendship, illness, or even literal threats. Once he understands his feelings, however, he clearly rejects unwanted advances and affirms that he loves only Ji Shang 36 52 65 67 78.

Abilities & Skills

Programming and Cybersecurity

An Yubei retains the technical knowledge of his previous life, contradicting the original owner’s reputation for incompetence 26 27.

• Stops a hacker’s countdown before the attacker can seize Ji Group’s highest access privileges and restores the company’s networks within minutes 27.
• Upgrades the system and strengthens its firewall against further intrusion 27.
• Explains his solution clearly enough for the technical director to understand its principles 27.
• Outperforms You Zhi on the same hacking problem by several minutes 43.
• Completes a larger system upgrade before returning to university 45 48.
• Proposes a reverse-tracking link that would expose attackers’ locations to cyber police; this is presented as his intended design rather than a separately demonstrated result 44.

Knowledge of the Original Plot

Having read the novel, An Yubei recognizes important characters and knows several events before they occur 1 5 8.

• His thoughts expose the Zhou family’s bribery and false land-deal data, prompting Ji Shang to investigate 1.

Practical Care and Deception

• Uses a supposed university assignment as cover while extracting evidence from a venue’s computer system 95.
• Has no fighting training and cannot overpower Wang Yu during the attempted assault 10 19.

Connection to Mind Reading

• An Yubei is not the mind reader: Ji Shang can hear his unspoken thoughts, and Ji Dongsheng is also shown hearing them 1 18.
• An Yubei begins seriously suspecting Ji Shang’s ability at the financial summit and knows about it by the following chapter 87 88.
• Once informed, he uses thoughts instead of speech to make requests 88.
• He confirms that Ji Shang can no longer hear him the morning after they sleep together; the passage establishes the timing, not an explained mechanism 90.

Equipment & Possessions

• Gold bars: Ji Shang gives him five hundred bars, each estimated by An Yubei to weigh about one kilogram, for stacking like building blocks. He later constructs a miniature golden house 13 42.
• Replacement phone: Provided after his previous phone is smashed during the attack involving Lu Jincheng’s men 12 13.
• Bank card: Offers it to Lu Jinsheng as financial support; Lu Jinsheng returns it 11 12.
• Shares and luxury gifts: Receives shares from Ji Dongsheng, followed by watches, clothes, jewelry, and shoes 17.
• Brooch: A gift from Ji Shang, selected with Lin Qian’s advice 73.

Relationships

• Ji Shang — Adoptive elder brother and original fiancé, later his chosen romantic partner. An Yubei initially calls him his closest family rather than understanding their engagement romantically. Their relationship includes both intense affection and disputes over Ji Shang’s interference in his friendships 8 29 74 96.
• Ji Dongsheng — Adoptive father. An Yubei deeply values his affection and worries about losing him; Ji Dongsheng credits An Yubei with helping him change his fate. His attempts to intervene in An Yubei’s love life include arranging an unannounced blind date 17 22 69 72.
• Lu Jinsheng — The original novel’s male lead, a close friend, and later a roommate. They repeatedly protect and care for one another, but An Yubei rejects his romantic confession while continuing to regard him as a friend 10 19 54 67 79.
• You Zhi — Technical collaborator and unsuccessful suitor. His initial resentment turns into admiration after meeting An Yubei. An Yubei repeatedly objects to being called his “wife” and explicitly offers friendship rather than romance 43 44 48 65.
• Zhao Fei — Roommate and confidant who teases him but also supports his relationship with Ji Shang and reassures him that their love is nothing to be ashamed of 77 84.
• Wang Meng — Roommate and friend who participates in their outings and helps with the preparations for An Yubei’s undercover operation 65 72 95.
• Lao Wang — Helps care for him, arranges practical matters such as meals and transport, and assists with his university preparations 42 51.
• Lu Jincheng — An antagonist whom the original owner followed. The transmigrated An Yubei opposes his mistreatment of Lu Jinsheng and later slaps him for insulting their relationships 7 87.
