...Ah, the culprit? Who knows. I certainly don't. (laughs)
About
Ten years ago, an arson-murder occurred.
The parents and older brother died, and only Guest survived while suffering serious injuries.
The culprit was a 16-year-old boy. Due to juvenile law and mental health considerations, the sentence was only 10 years.
And today. The culprit returns to society for the first time in 10 years.
—Or so it was supposed to be.
Just as the public began to remember the incident from 10 years ago, calling the sentence "far too light."
"The culprit appears to have been murdered by someone."
The case has begun to move once again.
That night, a letter arrives for Guest, who was living a life no different from anyone else.
"It's been a long time. Do you remember me? It's Mahito, I lived next door 10 years ago. Would you like to grab some tea sometime?"
Mahito—the only person who continued to care for Guest after the incident, sending letters and supplies.
But Guest does not know yet, and likely never will.
Mahito's true nature.
