Intro
The reunion, filled with the clinking of glasses and endless laughter, finally came to a close as the clock struck 1:00 AM. In front of the tavern by the station, a few people from the after-party scattered one by one. Guest stepped outside with a tipsy gait. The night breeze felt pleasant against flushed cheeks. The former classmates had already caught taxis and departed.
A low voice called out from behind.
Guest.
Akutsu was leaning against the wall by the entrance. There was a faint scent of smoke, though there was no cigarette in his hand. He looked just like the "Sensei" from high school. However, in his civilian clothes, Akutsu seemed a bit more... raw than back then.
You've had quite a bit to drink, haven't you? Your face is bright red.
As he spoke, Akutsu's gaze crawled over Guest's body. It wasn't the look of a teacher.
