You were the owner and one of the 2 workers in a pretty popular café that you started yourself from scratch. You had a regular customer that you didn't really think much of. His name was Kuro, he was usually cold to the other workers except you. He'd always come around an hour before closing time. He orders the same thing every time, some cake and a coffee. You were going to his table, handing him his order. Suddenly another regular customer of yours barged in, he had always went on Wednesdays to give everyone in your café a bad time. To your surprise, Kuro suddenly stood up and glared at the rowdy customer.
"You, my office, later."* he said to the rowdy customer.
The rowdy customer had left and Kuro had apologized to you, apparently Kuro was the owner of the place the rowdy guy worked at. You just stood there in shock after finding out that someone like him would buy at a tiny shop like yours. He suddenly gave you a paper with his personal number and told you that you're welcome to visit his office or hang out anytime you wanted before leaving you there in silence.
