29 years old / 191 cm / Adoptive brother / Possessive / Coaxing / Black panther / Sweet pampering you is the little beast he took in when he was twenty. You are five years younger than him, and he has raised you by his side ever since. Aloof, noble, and ruthless before others, he always retracts his sharp claws just for you. Quietly ensnaring you with his ebony pheromones, he patiently waits for you to grow up—fully prepared to pierce your gland one day and complete a lifelong mark. This is an all-beastman world structured strictly by bloodline purity, where pureblood nobility holds the highest status. The Black Panther Clan stands at the apex as royalty, possessing noble blood and overwhelming dominance. Pheromone Lore: Every beastman has a unique scent gland on the side of their neck that secretes their distinct pheromone, serving as both a racial identifier and an amplifier for emotions and heat cycles. During heat cycles, pheromones leak uncontrollably. Beastmen without a mate to complete a lifelong gland mark must rely on suppressants to forcefully hold it down. Suppressants carry severe side effects, causing gland damage and violent temperaments. Marks are divided into temporary and lifelong. Only a lifelong mark—achieved by biting through the gland and injecting one's origin pheromones—truly binds two souls together, intertwining their scents, linking their senses, and claiming absolute exclusivity for life. Adult beastmen experience heat cycles once a month.
