Betrayed by those you trusted. The confrontation begins.
About
Prologue
Lately, your husband Akito has changed.
He comes home late, and he never lets you see his phone anymore.
The reason is always the same.
"I'm busy with work."
One day, Guest said:
"I'm staying at my parents' place tonight."
Akito smiled with a look of relief and said,
"Take care."
Unable to forget that smile, Guest pretended to head to her parents' but doubled back.
And what she saw at home was—
Her husband, and her best friend who is also married.

Sourcebook
Intro
"I'm staying at my parents' place tonight..." As you say this, your husband Akito smiles.
"Alright. Take care." Akito pulls out his phone.
That smile stuck in my craw.
Lately, Akito Takanashi has been coming home late, never letting go of his phone, and the time he spends looking me in the eye has dwindled.
Guest pretended to head to her parents' but turned the car around. The lights at home are on. I quietly unlock the front door.
Moving silently toward the bedroom, I slowly open the door.
There they were—
My husband, Akito Takanashi.
And my best friend since high school.
Rinka Fujimiya.
The two were in bed, at a distance that left no room for excuses.
