After Lin Mian underwent gender differentiation, he didn’t know what happened to him at first. His body just felt a bit strange so he didn’t go to the hospital for examination.

His parents were not around, and he lacked physiological knowledge. When he went to class the next day, his classmates noticed there was pheromone leakage from him. Only then did he realize that he had undergone gender differentiation.

Soon the teacher knew about this from his classmates. The teacher took him to the infirmary and asked the school doctor to check his pheromones. He then gave him a brooch representing the omega gender and asked Lin Mian to pin it on his clothes.

Schools treated the protection and supervision of omega very seriously. Having them wear a brooch could prevent some inappropriate interactions.

Lin Mian’s situation was very special, so the teacher was very concerned about this matter and worried about whether Lin Mian would have any adverse reactions. Thus, within a few days, almost everyone in the school knew that there was a student in the second year that underwent gender differentiation at the age of eighteen.

Lin Mian was at a loss. He used to think that his family background was not very good, and he was even a beta, which made him not worthy of being with Xiao CongYi. However, he suddenly underwent gender differentiation. His mood was beyond words.

After Xiao CongYi found out about it, he sent Lian Mian a lot of things that an omega needed, such as suppression spray, pheromone suppression tape, and some books about pheromone.

He also advised Lin Mian not to stay so late at school in the future, and told Lin Mian that if he was afraid, Lin Mian could call him and he will send him home.

Omegas were fragile and needed protection in most people’s eyes. Even when it came to marking with alphas, omegas were the ones who would be marked……just like the interactions between him and Xiao CongYi in which he had always been in a passive role.

Lin Mian did not refuse the things that Xiao CongYi gave him. He picked up a bottle of pepper spray and looked at it, and he suddenly said, “Can an omega mark an alpha?”

Xiao CongYi was stupefied for a moment, he then smiled. “I don’t know. Do you want to try it?”

Xiao CongYi had never heard that omega could mark alpha, so he said that as a joke to tease Lin Mian. After all, he was an alpha. Even if he really let Lin Mian take a bite, it was not a big deal. Besides, he could use this to enhance the relationship between the both of them.

He never thought that Lin Mian would raise his head and reply with a serious tone. “Okay.”

……

After that, Xiao CongYi escaped. He told himself that it was impossible, but he couldn’t explain the strange feelings of his body.

He originally wanted to wait for Dr. Li’s next visit, and then ask him quietly, but he didn’t expect that Xi Ning discovered the teeth marks on the back of his neck. Xi Ning also made a temporary mark with Song Zhou when he was in estrus. Maybe Xi Ning can give himself some answers……?

Xi Ning couldn’t believe his ears and said in shock, “What did he…… do to you?”

The system was also stupefied. It was unable to detect the condition of Xiao CongYi’s body. It could only judge from his expression, words and actions that most of what he said was true. “Ah, this……as expected from the protagonist, he can even counter-mark……”

The system remembered that in the original story, there was no such setting. Was it because the plot had drifted a bit from the original plot and this situation deviated by itself?

Song Zhou had been paying attention to the situation here. He walked over and stood beside Xi Ning. “What’s the matter?”

An outsider came over, Xiao CongYi immediately recovered his usual appearance and pulled up his collar. “Nevermind, I will contact Dr. Li by myself tomorrow…… I’ll leave first.”

He turned and walked upstairs quickly, Song Zhou walked around and went in front of Xi Ning to block his vision. “Did he make you angry?”

“No no,” Xi Ning shook his head and frowned. “It’s just……”

Song Zhou didn’t care what happened to Xiao CongYi at all. He hugged Xi Ning and brought him along. “Doctor Li said that it’s best not to think too much about other things during estrus, because it will affect your emotions.”

However, Xi Ning kept thinking that if Lin Mian could mark Xiao CongYi, then why didn’t he mark Song Zhou that day?
