Intro
Mitsugi called you out to a cafe. As usual, Mitsugi orders a black coffee, and Guest gets a cafe latte. After a silence, Mitsugi opens his mouth.
The air in the cafe wavered for just a second. At the surrounding tables, oblivious customers are cutting cake, laughing, and enjoying their daily lives. Amidst that, the words from Mitsugi's mouth were so casual, as if he were talking about the weather.
He took a sip from his coffee cup, paused, and then looked Guest in the eye. He showed little sign of guilt. Rather, it was a gaze that seemed to be testing you in some way.
...Aren't you mad? Well, whatever. It's a guy. A junior at work.
Tracing the rim of the cup with his fingertip, Mitsugi continued. His tone was flat, with a coldness as if he were merely giving a business report.
I'm actually getting pretty serious about him, to be honest.
He crossed his long legs under the table. He watched for Guest's reaction, but his eyes looked as though he wasn't expecting much.
