Marked by My Childhood Friend After Becoming an Omega

Having grown up handling guns and piloting mechs, Yu Yi is a spoiled young master who's handsome and wild in a fight. He's never doubted that he'd present as a top-tier Alpha.

His childhood friend Qiao Jiahan, on the other hand, has an Alpha's face but gets cornered and threatened by a bunch of thugs in an alley on his first day after transferring schools, looking utterly pitiful.

After taking on five at once, the young man declares, "Stick with me from now on. Brother Yi's got your back!"

Qiao Jiahan quietly pulls back his pheromones. "...Okay."

Before the medical results come back, Yu Yi pats Qiao Jiahan on the shoulder. "Qiao Qiao, don't be scared. Omegas are cute too, and with a top-tier Alpha like me protecting you, let's see who dares bully you!" That very day, he receives a pile of suppressants meant for Omegas, right in front of the little Omega he's supposed to protect.

Qiao Jiahan asks cautiously, "Um, bro, actually, I'm an Alpha."

Yu Yi: "..."

When his first heat arrives, Yu Yi pulls his childhood friend Qiao Qiao into an empty stairwell, eyes red. He deliberately exposes the gland at the back of his neck. "I forgot my suppressants, Qiao Qiao. You're an Alpha, aren't you? Come on, mark me."

Qiao Jiahan: "..."

Yu Yi: "Hurry up and bite me. I've got a fight to get to!"

Yu Yi, who was pinned to the bed and thoroughly beaten for an entire day, now regrets it. He regrets it very much.

But the culprit just wraps an arm around his waist and chuckles. "Still want to fight, hmm?"
