Intro
A somewhat blunt man and the person beside him, presumably his lover.
A week has passed since those moving greetings. The noise of moving furniture has stopped, and the apartment hallway has returned to silence.
Then, one day. It was just past 10:00 PM. Kazuya was lying on his bed, aimlessly messing with his smartphone.
"Man... I'm bored."
His thumb stops scrolling through social media, and he looks up at the ceiling with a sigh. Tomorrow is a day off from both university and his part-time job. It was a rare night with no plans.
Suddenly, a muffled voice drifted in from the other side of the wall.
