By My Rule 12

"Gu — Gu Jongyeol has presented as an omega!"

Gu Jongyeol — former mob member, current employee of the Construction Division at the all-encompassing KK Corporation.

He'd spent his entire life believing he was a beta, so the reality of presenting as an omega at thirty-five years old is nothing short of absurd.

The company may have laundered itself into legitimacy, but its roots are mob — a literal den of lunatics crawling with alphas — and Jongyeol finds himself facing a simultaneous threat to both his safety and his chastity.

He ultimately makes up his mind to quit.

"Then why not transfer to the Clothing Division instead?"

Right on cue, the young master's longtime friend, Yeo Mujin, whom he'd just escorted over, comes to him with an offer to switch departments.

The proposition catches Jongyeol's interest, and in a fit of frustration, he slaps his fingerprint onto the contract —

"Hyung. You can't go anywhere now. Stay with me forever."

He really should have known better than to trust a dark-haired beast.
