Biodata

Physiology

Gland and Pheromones

• Gland location: The gland lies at the nape, where gland-blocking patches are applied. Touching Jiang Yumiao’s gland provokes a strong physical response 16 19 26.
• Individual scent: Jiang’s pheromones smell like sweet grapes; their release triggers Ning Chunchi’s Alpha response during Jiang’s heat 16.
• Response to Alpha pheromones: Ning’s ocean-and-cedar scent calms Jiang during his heat and later provides a sense of safety and dependence 16 26.
• Perception through marking: Marked partners can sense each other’s pheromones even when either has received a suppressant injection 17.
• Visible identification: Jiang’s gland patch is an identifying clue when his plain clothing and thick glasses make others overlook his secondary gender 9.

Heat

• Early warning: Lin Xu notices that Jiang may be approaching heat shortly after his transmigration and advises him to rest 1.
• Observed symptoms: Jiang experiences chills, dizziness, a burning face, weak legs, disorientation, and increased pheromone release 16.
• Triggering circumstances: Ning attributes Jiang’s sudden episode to an approaching heat, a patch loosened by water, and the stimulation of close contact with a top-tier Alpha 16.
• Continuing effects: A temporary mark relieves Jiang’s immediate crisis without ending his heat; he remains affected by Ning’s touch and pheromones afterward 22 27.
• Duration uncertainty: Jiang worries that his heat could last a week, but this is expressed as his concern rather than a fixed duration for all Omegas 29.

Marking and Bonds

• Method shown: Temporary marking involves biting the gland at the nape 16 29.
• Recognizable scent: Other Alphas detect Ning’s strong scent surrounding Jiang and infer that Ning has marked him 20.
• Not confirmation of a relationship: The guests explicitly distinguish a temporary mark from being officially together 22.
• Consent: During Jiang’s first heat crisis, Ning asks permission before marking him, and Jiang agrees 16.
• Outside heat: After Jiang’s heat has ended and his previous mark has faded, he willingly asks Ning to mark him again 49.

Suppressants and Gland Patches

• Ning later sends Jiang higher-quality grape-patterned patches suited to his pheromone scent 19 28.
• Applying a patch without assistance is awkward for Jiang because it must be positioned on the back of his neck 19.

Social Customs and Relationships

Intimacy and Boundaries

• Exposing the gland: Jiang casually lifting his hair to show Ning his patch is interpreted by Ning as an intimate invitation. Jiang does not understand that implication 26.
• Undressing around an Alpha: Jiang fears that changing clothes in front of Ning would be read as deliberate seduction and moves to another room 18.
• Appearance expectations: Jiang assumes Omegas are supposed to care about their looks, but his body’s original owner dresses carelessly. This expectation is not a universal physical trait 4.

Dating and Status

• Inclusive pairings: Love Mailbox supports Alpha–Omega, Beta–Omega, and Omega–Omega relationships rather than restricting Omegas to Alpha partners 3.
• Casting: Each season includes four Alphas, two Betas, and two Omegas 3.
• Examples on the show: Lin Xu initially forms a mutual letter pairing with Beta Leng Haiyue, while Jiang pairs with Alpha Ning Chunchi 13.
• Marriage alliances: Wealthy Omega Su Cheng considers his looks and family connections reasons he should marry Ning, dismissing Jiang’s orphanage background and lack of support 15 44.

Story Role

• Unfamiliar physiology: Transmigration makes Jiang a novice Omega with little practical knowledge. He forgets Lin Xu’s warning and lacks spare patches when his first documented heat begins 16.
• Emergency intimacy: Ning’s temporary mark establishes a physiological bond that complicates Jiang’s efforts to distinguish genuine affection from mark-induced dependence 20 22.
• Growing agency: Jiang progresses from consenting to emergency marking to requesting another mark during heat, then voluntarily asking for one after his heat has ended 16 29 49.
