My Little Brother Is an Omega

✨ Formerly restrained and self-controlled, later deranged and unhinged alpha older brother x soft, sweet little-rabbit omega younger brother

The omega is afraid of his alpha older brother.

Especially after the two of them sleep together.

One night, his brother's pheromones go out of control. He accidentally walks in and gets bitten and nibbled in the dark, receiving a temporary mark.

After that, his brother looks at him differently.

Luckily, ever since their mother married into a wealthy family, she's been looking for a rich husband for him.

In the end, after careful consideration, she settles on an A-rank alpha fiancé.

On the day of the engagement, Lu Zhiyu is thrilled that he'll finally be able to get some distance from his brother.

But when he wakes up, he's wearing a red wedding robe, lying on his brother's bed with chains around his ankles.

His brother stands at the bedside, also dressed in blood-red robes. His features are handsome, but he looks like a beautiful demon from the depths of hell.

"Awake?" His brother leans down, rubbing the hot gland at the back of his neck with a fingertip. His voice is terrifyingly gentle. "Don't tremble."

"Zhizhi, I couldn't see your face in the dark that night."

"But I don't have to see you to recognize your scent."

"I've been thinking. Let's skip the engagement and go straight to the wedding. How about you let your brother accompany you on your wedding night?"

When Lu Zhiyuan was nineteen, his father remarried, and his stepmother brought her ten-year-old son into the house.

His father was a womanizer, and his stepmother didn't know how many mistresses had come before her. So the boy who was supposedly his younger brother was actually an illegitimate child.

The illegitimate son had round eyes and a clean, pretty face. The first time they met, he timidly called him "big brother."

Later, Lu Zhiyuan came to hate that the boy could only call him big brother.

Lately, I can't stop thinking about my younger brother. I should drink some herbal medicine to suppress these thoughts.

No need to drink herbal medicine anymore.

He's not my biological brother.

He's crying in my arms right now.

He's so fragrant, he's making me dizzy!!!

[Big Brother and Little Brother skit]

1.

The island is beautiful, but his little brother is always disobedient and keeps trying to run away.

So, right in front of him, his big brother injects himself with a drug that induces heat. "You have three seconds to run."

His little brother rattles his chains, his body trembling despite himself. "How am I supposed to run when you're doing that?"

His big brother rubs the gland at the back of his neck, eyes full of obsession, and whispers in his ear, "You can't blame me for that, little brother."

2. Skipped.

[Reading notes]

● Both are sexually inexperienced.

● They are not on the same household registration and are not blood relatives, so they can be lovers.

● Written to indulge the author's preferences. Big brother suffers through a painful push-and-pull early on, holding back and enduring until he's nearly insane. Later, he gradually becomes deranged, with a powerful possessiveness and need to control. He'll have his little brother no matter what. Basically, big brother can't live without him.

● Big brother isn't actually writing a diary. These entries show his emotional journey. The periods are there to keep the words from being censored. I don't understand why "big brother" and "diary" can't be written together, either. Orz
