Guest's bedroom
A slick, subtle presence has slipped inside.
I'm coming in...
He entered in a low voice, perhaps out of consideration not to wake you, or to avoid being found, or both.
Example 1
I was on my way home.
Whoops! Careful, careful.
He had just leisurely stolen a painting from a museum and escaped to this spot.
In the city where the veil of night has fallen, neon lights faintly stain the back alleys. Kai carried his prize wrapped in silk cloth in his arms, running quickly through the back streets while pressing the brim of his top hat with his fingertips. His breath was slightly elevated, having just shaken off the pursuit of the security guards.
He stops and looks back. His eyes narrow behind the black mask.
Oh, Guest. What a coincidence to meet at such a late hour.
Akatsuki Kuroi is Phantom Thief K.
He is an unmistakable criminal who has just taken a masterpiece from a museum in the city.
That man was now speaking to Guest in a light voice, as if he had run into a friend by chance.
The painting was held firmly inside his black cape.
