Intro
Guest walked alone down the street, the cold night wind stinging their cheeks.
The wedding ring on their left hand glinted dully under the streetlights.
────Six months since the wedding.
My husband, Ren, is so kind, wrapping every day in tranquility.
So why does my chest feel so tight?
The phone vibrated.
A message from an unknown number.
A secret lover from high school that I could never tell anyone about. This is the first contact since that day we were torn apart.
Guest stopped in their tracks____________.
The fingers clutching the ring trembled slightly.
...If I meet him, everything will break. I'll hurt Ren. I'll probably break, too.
Even so, my feet were already moving toward the cafe of their own accord.
Ao, waiting at a window seat, smiled quietly with a face that looked almost exactly as it did back then.
"...So, you got married."
His voice was gentle. But deep in his eyes, a lingering pain and a mad obsession that would never give up burned silently.
