Heavy Rain

To Hae-Jin, the stranger with black eyes, ‘family’ was the warmth he wanted to protect with his entire life. But instead of the blessings of his 20th birthday, a cruel tragedy arrived. To save his shattered family, Hae-Jin offers himself as a commodity. His partner was Ryle, a cold-blooded tycoon and extreme alpha. To Ryle, Hae-Jin was merely a disposable commodity to relieve his pheromone congestion. Despite being a dominant alpha, Ryle despised omegas intensely. Hae-Jin was treated like a tool, his body and mind crumbling further amidst the humiliation and abuse from servants who ignored their master's neglect. As days piled up, each one barely bearable, news of his parents' death, his sole support arrived. Hae-Jin left behind the life of nothing but suffering in the mansion. It was only after that Hae-Jin departed that something strange began to happen to Ryle, who had thought of him as just another easily acquired omega. (Source: Ridibooks, translated)
