As an A-level top-tier Alpha, Qin Cheng is 'united' with his classmates and 'respects' his teachers. He carries the burden of being both the school grass and the school tyrant.
On the day of his differentiation, he was diagnosed with Omega pheromone insensitivity, which means he has no susceptible period and is not affected by Omega pheromones.... more>>

Until one day, a tall, long-legged, and pleasant-smelling Alpha deskmate transferred to his class.
Qin Cheng's susceptible period is drawn out.

Qin Cheng: ???

Doctor: "The two of you have an extremely rare Alpha pheromone compatibility. You need to help each other through every susceptible period until Jian Heng finds his Omega."
Qin Cheng: "Then what should I do after that?"
Doctor: "Er... Currently, medical advice suggests that you take medication for a long period of time."
Qin Cheng: ...

Qin Cheng has been straight for eighteen years, and never expected to become good brothers with Jian Heng, whom he initially couldn't stand at all!
Even more unexpectedly, his good brother actually fell in love with him!!
What he didn't expect most of all was that he didn't even realize when he became bent!!!

Jian Heng, this person, is so damn cunning! He likes it so much! <<less

Yu Chengsong from No. 1 Middle School is a top-level Alpha selected from thousands of people. He is 1.89 meters tall and has long legs. He is good-looking, has good grades, and is capable of fighting against seven people at the same time.... more>>

The only downside is that, it is rumored that Brother Song is not interested in O.

One day, this big shot, who used to sit alone, was suddenly forced to have a deskmate by the homeroom teacher.

This warrior's name is Yin Gu. He is also 1.89 meters tall and has long legs. Compared to Yu Chengsong's rebellious and unruly face, which looks like he’s not someone people want to mess with, Yin Gu is handsome and gentle. He’s always smiling at everyone and is loved by all the teachers and students in the school.

Only Yu Chengsong knew that his new deskmate was a complete villain. The better student he’s being in school, the more vicious he will fight after school.

Even with that harmless handsome face, he kept talking dirty to him all day long, and his words were extremely naughty.

As a powerful top-level Alpha, Yu Chengsong can easily overcome his susceptibility period. Until he had been in contact with Yin Gu for a month, and his susceptibility period suddenly broke out early.

This susceptible period is different from previous ones. It is more aggressive, and the pain and suffering are countless times more severe than before.

Yu Chengsong was taken to the infirmary by Yin Gu, and he was so distressed that he wanted to commit self-harm.

Yin Gu grabbed his hand, leaned forward slightly, revealing a part of his neck, and said with a smile, "Try it.”

——

The Alpha’s susceptible period can be resolved by Alphas marking each other, and as long as they can endure the extreme pain for half an hour, they will be fine.

But almost no one can endure this half-hour of pain.

One time, Yin Gu was in a susceptible period.

Yu Chengsong touched the back of his neck and teased, "If you don't cry out in pain, you'll be on 'top' from now on.”

Yin Gu raised his eyebrows: "There is even such a good thing?”

After one night, Yu Chengsong regretted it so much that he hammered the wall, feeling helpless and furious.

Why doesn't the marking at that time hurt??? It was not mentioned in the physiology book ah, f*ck!!! <<less
