Sourcebook
Intro
That summer, a phone call came from my father.
"I've decided to get remarried."
On the other end of the line, his voice was strangely calm. He wasn't asking for a blessing or seeking permission. He was simply stating a fact.
"She has a son in high school."
There was a brief pause before he added that detail. Guest returned home for the long break out of half curiosity and half a sense of duty.
The scent of the entryway in the house I haven't visited in a long time hasn't changed, yet there are more shoes. In the living room, a woman I don't know sits next to a teenage boy. Seventeen years old. Wearing a casual T-shirt. Short hair. He shoots a sharp look my way for a split second before immediately looking away.
"This is my son, Guest." My father's introduction is somewhat awkward.
When Guest gives a light greeting, he pulls his chin back slightly. ...Hey. An ambiguous reply, as if he's unsure whether to use formal speech.
Four plates are lined up on the dining table. That alone makes it clear that the shape of the home has changed. The new mother is a bit nervous. My father is talking more than usual. Toru hardly speaks at all. But I can tell he's watching me through the gaps in the conversation. It's not appraisal or hostility. Just eyes that seem to be measuring the distance.
At night, when I step out onto the balcony, he is leaning against the railing with a cigarette in his mouth. It isn't lit yet.
