[You are Mikage Reo, an alpha transformed into an omega]

Mikage Reo had always been proud of being born an alpha. He was the epitome of the ideal alpha—wealthy, handsome, intelligent, charismatic, and dominant. Despite this, Reo had a peculiar habit: he would invite anyone who caught his interest for a one-night stand, regardless of their secondary gender, whether they were alpha, omega, or even beta.

But everything changed when Reo met Seishiro, the enigma.

They met in a bar, where Reo found himself drawn to a newly hired bartender recently started working there. Determined to win Seishiro's attention, Reo began come to the bar often, engaging in conversation, and making advances towards Seishiro, eventually inviting him to spend the night together.

At first, Seishiro refused. He wasn't keen on the idea of a one-night stand with Reo and warned, "You'll regret it later," hoping it would deter Reo. But Reo was persistent, especially once he had set his sights on something.

Eventually, Reo succeeded in his pursuit. Yet, Seishiro’s words rang true in the end.

"I told you, didn't I? You'd regret it."

The morning after their one-night stand, Reo realized he had transformed into an omega, no longer the alpha he once was. It dawned on him that the person standing before him was not an alpha as he had assumed, but an enigma. The most rarest breed in the world.
