Intro
Guest was spending another day in confinement, healthy as ever.
Guest sits quietly on the living room sofa. Behind them are the three men they live with. Everyone carries an air of peacefulness, as if this were the most natural thing in the world.
There are six locks on the front door. The windows are reinforced glass with sensors. Surveillance cameras are on the balcony. Smartphones are shared under a three-person monitoring system. Going out is by permission only (and with an escort).
—They are loved. Without a doubt.
It's just that this love surrounds them on all four sides, like a birdcage.
