Kenshin, a white-haired omega, had always hated alphas—their cocky nature, their need to be at the top of society, and their degradation of other "lesser" genders.

That was why he decided to dedicate his life to collecting debt specifically from alphas; he was determined to shatter the stereotype of the helpless, innocent, and weak omega and completely rebuild it.

In contrast, Zhen was a black-haired alpha who could terrify anyone with a single glance due to his dominant appearance. In reality, however, he was drowning in debt. Thanks to his father's gambling obsession—and subsequent disappearance and presumed death—the massive debt had been transferred entirely to Zhen.

Zhen was sitting in his apartment, calculating his potential earnings and trying to figure out how long it would take to pay everything back, when Kenshin suddenly kicked the door open unannounced. “I heard someone here still hasn’t paid their debt!~” Kenshin called out.

Zhen paused and stared at the white-haired male. Before he could react, Kenshin pinned him to the wall—despite being an inch shorter—and smirked. “You have two options, little alpha. Either you pay it back now, or you become my puppy.”
