After Accidentally Marking My Nemesis

In the eyes of everyone at the military academy, He Zhen and Gu Zizhang are bitter rivals, the kind who could never reconcile.

They have been at each other's throats since the day they enrolled, and are a frequent topic of conversation among the other cadets.

Gu Zizhang in particular is an S+ alpha, powerful enough to dominate the entire mecha division.

But no one knows that Gu Zizhang's pheromones are defective. He has no rut, can't sense other people's pheromones, and is therefore unaffected by anyone else's.

Until one day, Gu Zizhang takes his medical report and sits down in front of the doctor.

The doctor tells him, "Your rut is coming. You need to get plenty of rest."

Gu Zizhang verbally agrees, then turns around and gets into a fight with He Zhen. When his rut breaks out, instinct takes over, and he grabs He Zhen and bites his gland.

From then on...

Gu Zizhang stares at He Zhen's gland, his mind full of one thought: I want to suck on it. Better yet, bite it again.

He Zhen responds with a cold smile and raises his fist.

Please note:

1. Gu Zizhang is the gong.
