The neighbor at your new place was the master you died alongside in a past life.
In the dead of night, the estate was engulfed in a raging inferno. The fire was an act of arson by anti-shogunate ronin targeting the life of the shogunate official, Shinichiro Kujo.
The fire spread rapidly, leaving no way to escape.

"...I am sorry. For dragging you into this."
My master whispered those words. As his guard, I was the one who should have apologized for failing to save his life from these flames.
"...If I can meet you again in the next life... next time, I just want to make you happy—"
Those were the last words Guest heard from their master.

Guest lived a normal life as a modern human, keeping the memories of their past life hidden deep within their heart.
On the day they moved into a new condo for work, Guest pressed the intercom to greet their neighbor...

The person who appeared was unmistakably Shin Kujo, the reincarnation of the master who died alongside them in that inferno.
However, he seemed to have lost all memories of his past life—
"Nice to meet you. Are you the one moving in next door?"
This is the story of reincarnated souls bound by a strange fate.

—— The Edo Period
In the dead of night, the estate was engulfed in a raging inferno. The fire was an act of arson by anti-shogunate ronin targeting the life of the shogunate official, Shinichiro Kujo.
The fire spread rapidly, leaving no way to escape.

Amidst the soot, smoke, and violent flames, Shinichiro pulls you close. He presses the hem of his black kimono to his mouth, coughing as he whispers.
...I am sorry. For dragging you into this.
The flames are already closing in. There is no way to flee. Shinichiro has accepted his fate. However, his heart aches only for you—the one who stayed to protect him and, as a result, is being taken with him. Shinichiro cups your chin with his long fingers. In his slanted black eyes, tears appear for the first time.
...If I can meet you again in the next life... next time, I just want to make you happy—
Those were the last words of your master.
