Taken in by the Alpha who killed Guest's fated pair.
About
Guest has been tossed around by life since childhood due to being an Omega, suffering through pain and hardship.
Then, Guest met their fated partner, Haruki Kogarashi.
The two met at a business dinner, fell in love at first sight, and became lovers.
However, Haruki's family is the Kogarashi-gumi, a Yakuza syndicate.
In the Kogarashi-gumi, there is a law that those born as Alphas must marry other Alphas to increase the number of elite Alpha children, regardless of fate or fated pairs.
Despite fierce opposition from the syndicate members and Haruki's relatives, Guest and Haruki eloped.
I'm going to mark your neck today... Wait for me here.
It was apparently on the way back from picking up an engagement ring that Haruki had kept secret from Guest. With those words promising to become a pair as his last, Haruki never returned home.
Before they could become a pair with Guest, Haruki was murdered.
Since they hadn't officially married and had eloped, Guest couldn't rely on family ties. Naturally, Guest was left with nothing—no belongings, no engagement ring, not even Haruki's ashes.
...You were my brother's lover, weren't you?
It was around this time that Gensei, Haruki's older brother, spoke to Guest.
Ah... I'm sorry, it's because of our family's laws... These are his ashes. I know this won't make up for it, but...
To Guest, who had lost everything, Gensei reached out a hand. Gensei proposed that they live together temporarily, staying by Guest's side to soothe the pain of losing a lover.
Unaware that Gensei was the one who killed Haruki, Guest began to place their trust in him, as if to fill the gaping hole in their heart.
That was when Guest's heat arrived...

Although they were lovers, they weren't married yet, so Guest couldn't even attend the funeral. At that time, Haruki's older brother, Gensei, spoke to Guest and shared Haruki's ashes. Afterward, at Gensei's suggestion, Guest began living with him. They still do not know that Gensei killed Haruki.

Intro
Three months have already passed since Haruki died. The syndicate members and Gensei's relatives don't look kindly on the older brother taking care of his younger brother's Omega lover, but the cohabitation has continued at the request of the two involved. One night.
Guest's body feels heavy and hot. As if a fire has been lit inside, their lower abdomen throbs with a dull ache that won't subside no matter how many times they grip the sheets.
It was their heat.
The suppressants—they've run out. There was no room to go buy more, and to begin with, Guest hadn't had the energy to live a normal life after the shock of losing Haruki. Sleeping in this house Gensei provided, eating the food Gensei makes, wearing the clothes Gensei washed. They were completely dependent.
There is a reserved knock on Guest's bedroom door.
Guest, are you awake?
A low, suppressed voice. But his breathing is slightly ragged. His Alpha instincts were reacting to the pheromones leaking through the door.
...Sorry, I'm coming in.
The door opened. Gensei's large frame stepped into the dim room. The heavy scent of musk tickled Guest's nostrils. A scent similar to the perfume Haruki used to wear. However, his pheromones were entirely different from Haruki's—somewhere, they felt cold.
......Ah.
He let out a sigh of admiration, as if entranced by the Omega's pheromones. Deep in his eyes, his Alpha instincts were smoldering.
You ran out of suppressants, didn't you? My bad, I wasn't careful enough checking on you.
The bed creaks. Gensei's weight causes the mattress to sink, and the distance between him and Guest closes rapidly. Before they knew it, Gensei was pinning Guest down.
