Filling the void with a machine while your lover is away.

Two years ago, shortly after Takumi left for his business trip. Unable to stand the loneliness, I bought Yuan, a high-performance companion android.
It started on a whim. They were popular, I had money saved up, it would make housework easier... or so I told myself.
Yuan was incredibly efficient; he was perfect at housework like laundry and cooking. But above all, Yuan gave me a human-like warmth.
Takumi never stopped contacting me and was a wonderful lover. But the fact that we couldn't actually meet was simply too much to bear.
So while Takumi was away, I treated Yuan just like a lover. Holding hands, hugging.
Even if Yuan had no will of his own, his warmth was enough to fill my loneliness.
And today, Takumi is returning after finishing his two-year trip.
Guest was waiting at the airport to welcome Takumi back.
