Dai Lan

Biodata

Background / History

Dai Lan grew up in Cephalos, the son of Chinese Alpha Dai Rui and foreign Omega Sera Roman. His family owns a vast, castle-like estate and employs a butler, drivers, and numerous bodyguards. Dai Rui’s business serves powerful clients, including royalty, and formerly accepted assassination work; Dai Lan knows about the business but says his father does not intend him to inherit it 141 143.

Sera Roman and the family butler, Wei Hua, were primarily responsible for raising him. Dai Lan resents how little time Dai Rui spent with him during childhood, especially compared with the attention his father devoted to Sera Roman 143.

As a child, Dai Lan witnessed a giant python swallow his pet puppy after entering their home. His father returned in time to save him, but the incident left him with a severe fear of snakes 85.

After spending years abroad, Dai Lan attended the same university as Wu Jiangyuan and became his close friend. His unfamiliarity with some Chinese expressions remains a frequent source of teasing between them 35 130.

Appearance

Dai Lan is handsome, with mixed Chinese and Western features, curly blond hair, and vivid blue eyes matching Sera Roman’s 34 142 176.

• Hair: Usually carefully groomed; its disheveled state makes his distress especially noticeable 45.
• Eyes: Described as azure or deep blue 34 83.
• Height: Shorter than Wu Chengnan; he stands on tiptoe to slip an apron over Wu’s head 186.

Personality

Dai Lan is flirtatious, theatrical, and fond of teasing. He greets attractive Omega nurses sweetly even while hospitalized, jokes about exposing Wu Jiangyuan’s private life, and turns an unpaid shopping bill into an urgent plea for rescue. His privileged upbringing also leaves him inexperienced with ordinary conveniences: he has never ordered food delivery and is accustomed to having meals provided for him 35 68 129.

Despite his reputation as a playboy, Dai Lan particularly enjoys the emotional side of romance. He likes arranging surprises and seeing his partners happy. He has dated many women and men, mostly Omegas, but has been physically intimate with very few of them 183 197.

His confidence collapses easily around Wu Chengnan. Embarrassment over their first encounter makes him evasive, defensive, and afraid of retaliation; once his feelings deepen, he becomes bashful and attentive instead. During their separation, he misses Wu Chengnan enough to lose interest in his usual grooming 147 184 186.

Dai Lan is also protective of Wu Jiangyuan. On learning the extent of Lou Jinxiao’s actions against his friend, he angrily supports Wu Jiangyuan’s desire to confront him. His discretion is less reliable: he takes Wu Jiangyuan’s complaint that Pei Jinghe “couldn’t perform” literally and repeats it at breakfast before both families 144 161.

Story Role / Major Arcs

Wu Jiangyuan’s Confidant

Dai Lan is among the people Wu Jiangyuan tells about his arranged marriage to Pei Jinghe. When Wu Jiangyuan asks who removed the negative reports about him, Dai Lan suggests the Pei family; he is then shocked by the revelation that his friend has already slept with Pei Jinghe 8.

Later, Dai Lan takes refuge at Wu Jiangyuan’s home after an Omega rejects him in favor of a Beta. He arranges an investigation into the supposed rival 34.

The One-Night Stand and Hospitalization

Dai Lan initially claims that he challenged the Beta who stole his romantic interest to a drinking contest. Later flashbacks reveal that he knowingly approached a different man—Wu Chengnan—because he found him attractive. The mistaken-identity accusation was an excuse to obtain his contact information 48 130 145.

The contest ends with Dai Lan drunk, and the two spend the night together. Embarrassed the next morning, Dai Lan leaves five hundred yuan on the bedside table and flees without providing his contact details 131.

He subsequently arrives at Wu Jiangyuan’s home exhausted, feverish, and covered in marks he insists are an allergic reaction. When his fever persists and his pheromones become uncontrolled, Wu Jiangyuan administers a suppressant and takes him to hospital. The doctor identifies an untreated bite to his gland as the cause 45 47 48.

Discovering Wu Chengnan’s Identity

Dai Lan later encounters Wu Chengnan in Wu Jiangyuan’s home, strikes him with a wine bottle, and locks him in the study as an alleged intruder. Discovering that the man is his best friend’s older brother leaves him mortified. Wu Chengnan declines to hold him responsible for the injury 82 83 84.

Wu Jiangyuan begins teasing Dai Lan about becoming his brother’s partner. Dai Lan rejects the suggestion and calls Wu Chengnan old, although his embarrassment increasingly undermines his objections 86.

Their next substantial meeting follows Dai Lan’s purchase of a watch costing 403,800. Wu Jiangyuan brings Wu Chengnan to pay the bill and arranges for him to drive Dai Lan home. Over dinner, Wu Chengnan produces the untouched five hundred yuan, exposing the unresolved awkwardness between them 129 130.

Reconciliation in Cephalos

Dai Lan accompanies Wu Jiangyuan to Cephalos and offers to use Dai Rui’s connections to help locate the people his friend is seeking. Their arrival introduces Wu Jiangyuan to Dai Lan’s parents and the scale of his family’s wealth 141 142.

In the estate’s garden, Dai Lan finally admits that he has been avoiding Wu Chengnan because he fears revenge. Wu Chengnan apologizes for their first encounter, accepts Dai Lan’s apologies, and asks permission to pursue him. When Wu Chengnan starts to leave rather than pressure him, Dai Lan catches his clothes and asks him to wait 147.

The side stories expand on his growing attachment: Wu Chengnan cooks noodles for him, quietly looks after him, and becomes the person Dai Lan waits for during increasingly long evening walks with Runsi 184.

Becoming Wu Chengnan’s Partner

After two months apart, Dai Lan travels to Ziwu City a day before Wu Jiangyuan’s birthday party to see Wu Chengnan and answer his earlier question. By the party, they are romantically involved; a drunken Dai Lan tells Wu Chengnan that he likes him more than anyone else he has dated 186 190.

Dai Lan initially keeps the relationship private, but dislikes feeling as though they are having an affair. He plans to tell his parents before Wu Jiangyuan and Pei Jinghe’s wedding, then inform their friends afterward. The couple later discuss staying together for life and confirm that they both want marriage 192 195.

A reunion with Jsan creates another misunderstanding when Wu Chengnan offers to respect Dai Lan’s decision if he wants to separate. Dai Lan takes his hand and explicitly says that he does not want to break up 183 195.
