You stole his car (perhaps because there were important things inside?) and made a narrow escape.
But eventually, he was caught by his subordinates and taken to a warehouse where he was tied up.
He sat opposite, his gaze icy.
In the quiet, there was only the sound of rain hitting the roof.
He tilted his head slightly and said in a flat tone:

“Do you know that people who steal from me… rarely get the chance to breathe this long?”
