The Responsibilities of an Eldest Brother [Interstellar]

My new story, After Discovering the Disabled Top Student's Secret, is now available. Complete and finished! Please leave a good review if you bought the whole series! Interstellar ABO, younger man raises older man. Shen Jiang first met Cen Xing when Cen Xing was only nine years old. That night, Shen Jiang's father, who was rarely home, suddenly brought a little boy back with him. The boy was tiny, with soft silver-white hair falling to his shoulders. He hid timidly behind the adult, warily surveying his surroundings. "A-Jiang, this is the orphan of a comrade-in-arms. He'll be living with us from now on. Treat him like your own little brother and take good care of him," his father said. "Don't worry, Father. I'll take good care of him." Shen Jiang took the seemingly sweet and harmless child by the hand. He deliberately crouched down, stroked his soft hair, and gently coaxed him. "Little guy, from now on, I'm your big brother. If anyone gives you a hard time, tell me." - Shen Jiang had long accepted that he was a beta. He never expected that his gender differentiation would simply come later than an ordinary omega's. On the night he differentiated, Shen Jiang hid helplessly in a dim alley, overwhelmed by unfamiliar sensations in his body and forced to breathe in an overpoweringly sweet scent. Trembling, he vaguely made out a man standing in the darkness: Cen Xing, the boy he'd raised since childhood, now known as a human weapon. Cen Xing was no longer the dull child he'd been. His snow-white hair fell just to his shoulders, and the wildness in his eyes was barely contained. Cen Xing's powerful alpha pheromones drew closer with every step. Shen Jiang tried to retreat, but there was nowhere left to go. "Shh, be quiet. There are plenty of hungry alphas outside the alley. They've all caught the sweet scent of their eldest brother's pheromones." The man's voice was husky and seductive, its final syllable rising slightly. "Thank you for taking care of me all these years, Big Brother. Now it's my turn to take care of you." Younger man raises older man! Younger man, younger man, younger man. A silver-haired doggo who bites x a man with a surprising side... (I don't know how to describe him), with an eight-year age gap. P.S. * I wrote quickly during serialization, so there may be grammatical errors. I'll revise it thoroughly after it's finished. * A little bit of a serious drama. * The top has an animal form: a wolf. * Younger man raises older man. Nothing inappropriate happens before the top comes of age (including kissing, and so on). Theme: Accompanying and supporting each other as they reach the pinnacle of their careers.
