Pheromones are concentrated on the back of a person's neck.

The pheromone smell is strongest there.

General omega pheromones will be alpha attractive, but in normal times, the attraction will not be too obvious, and alphas with strong self-control can be controlled, and they don't care about this temptation.

But – pheromones have an active period.

In this period of alpha, self-control will drop exponentially, almost equivalent to nothing, if you feel a strong omega pheromone at this time, the powerful alpha may immediately pounce on it and possess the mark.

Of course...... It's not inevitable.

As soon as an alpha marks an omega, it becomes immune to other omegas.

Omegas that are labeled with alpha will also be unaffected by other alpha pheromones.

Markers, which are divided into temporary markers and permanent markers.

Temporary marking – biting the back of the other's neck.

And the permanent mark is to have a relationship.

The young man's lilac eyes narrowed slightly, his glass-like eyes were not shocked, but his thin lips were slightly pursed, revealing a soft and cute dimple on the side of his white and tender cheeks.

But it was just a pursing of his lips, he wasn't smiling, and his pretty eyes were cold.

Odd.

Today is not his pheromone active period.

There is an active period when he becomes an adult, he has just come of age, and he has only experienced an active period once, and he is a residence where he stays outside by himself.

The active phase passed smoothly without any desire to mark omegas.

He didn't know what it would be like.

But at this time, staring at the back of the girl's neck, the young man bit his beautiful lower lip slightly, and his breathing paused slightly.

The glare rested on the back of the neck until the girl had eaten and lifted her eyes to meet his.

The boy clearly saw that she trembled almost subconsciously before stammering:

"Ah Ran...... You, have you eaten well? ”

The young man narrowed his eyes and hummed faintly.

Yu Chu blinked, he didn't expect him to answer.

In the past, the original owner endured his nervousness and tried his best to talk to him, but he never paid attention to it, and never even said a word......

At this time, hearing the simple syllables, the body actually trembled again, and subconsciously shrank back.

Yu Chu was helpless, so he had to whisper:

"I'm eating, I'm ...... I'll go first. ”

She stood up cautiously, and the robot moved over and took the empty bowl in front of her.

The young man's beautiful eyes were still looking at her quietly, and under the long and thick eyelashes, the jewel-like pupils looked a little meaningless.

The morning sun is a pale gold, reflecting the young man's fair and delicate cheeks, which looks quiet and beautiful.

Yu Chu turned around and left for no apparent reason.

The person behind said, "Wait." ”

A clear, low-pitched voice.

Yu Chu was stunned, turned his head, and faced the young man's pair of beautiful and charming glass pupils, he stood up slowly, his slender height showed a bit of oppression, but a shallow smile appeared on his fair face.

The dimples are exposed, but the absence of alcohol is intoxicating.

Light purple eyes looked at her quietly, flaxen-colored broken hair covered her delicate eyebrows, and the young man's voice was as sweet as candy, sounding like an invitation, but revealing an irresistible bewitchment: "Come with me." ”

After a pause, he slowly bit the words again, and said softly:

"Sister...... Sister. ”

Yu Chu looked at him blankly.

As if pleased by her sluggish expression, the smile on the young man's face became sweeter, his head tilted, his thin lips slightly hooked, and his voice seemed even more bewitching.

"Sister?"
