[Older Love Interest, Pseudo-Incest, Alpha/Omega Romance, Seven-Year Age Gap]
Yan Huilin had spent twenty years as the youngest son of the Yan family, only to be told on the eve of his birthday that he was nothing but a fake young master who had usurped the place of the real one.
His adoptive father revised his will overnight. His adoptive mother kicked him out, and the real young master ruined his acting role with a single phone call. Even his birth mother disliked him because her husband had been jailed for taking bribes.
Rain poured down, and he had nowhere to go. Then a black umbrella suddenly sheltered him. He looked up. The man still looked weary from a long flight, but his handsome features were unmistakable.
It was Yan Chao, his Alpha older brother and the heir to Yan Group.
He held out a hand and said, "Come home with me."
*
Ever since he had presented as an Omega, his relationship with his older brother had grown increasingly distant. The hand held out to him on that rainy day gave him courage, and like he had as a child, he returned to Yan Chao's side.
He thought they could go on like this forever, until he accidentally overheard a doctor say that Yan Chao had a pheromone-specific recognition disorder.
Only after pressing him again and again did he learn that Yan Chao might not live to see forty, and that his own pheromones were the only medicine that could save him.
He wanted to save him, but Yan Chao merely stopped signing, looked up from a pile of documents, and said, "Stop this. Do you know what pheromone therapy means?"
Yan Huilin braced both hands against the desk and said urgently, "So what if it means a lifelong mark? I just want you to stay alive!"
