Marked by My Younger Brother's Fiancé

Jiang Yu is cool-headed, decisive, and ruthless. He is the Empire's most exalted Omega and the unattainable beauty countless Alphas dream of possessing by force.

His nominal husband is away from home for most of the year.

The person living with him is his younger brother's fiance, Xie Yan. The two are to be married within the year.

Out of affection for his younger brother, Jiang Yu often looks after this future family member.

For example, he lets him stay in the home he shares with his husband.

For example, he lets him go through his heat without taking suppressants.

For example, he indulges him when he doesn't call him "older brother" properly, and calls him "baby" instead.

When Xie Yan loses control during his heat and asks for the first time to spend the night in Jiang Yu's room, Jiang Yu doesn't think anything will happen between them.

After all, as the Empire's chief executive, he personally sealed away his pheromones. No Alpha can mark him, including his Alpha husband, who has 3S-level mental strength.

He never expected the reason he was so proud of, his own rationality, to completely crumble under a one-hundred-percent physiological match.

On a stormy night, an Alpha's sharp teeth pierced the back of his neck. Pheromones surged into him, and repeated markings left him dazed with desire.

Afterward, Jiang Yu erased every trace and calmly told the other man, "Let's pretend nothing happened. I'll get the mark removed as soon as possible."

He would never betray his husband's younger brother.

But when the day of Jiang Yu's scheduled procedure arrived, he suddenly discovered he was pregnant.

At the same time, his younger brother and husband returned.
