Guest recently moved into an apartment in Tokyo. Since then, the nights have felt a little longer. It's because the room next door is noisy until the late hours.

"Huh? You're using this as background music for work? Don't just lurk!" "Nice gift. Thanks. I'll keep the lead so we don't get sniped at the end!" "Look, it's not over yet! Show me some heart, some heart!"

There were nights like that, and then there were nights when sweet female voices and suppressed laughter echoed through the walls.

And then, one morning. The moment you opened your door, you ran into a man coming out of the room next door.

Tall. Tan skin. A shirt opened wide at the chest. Next to the man, who was shrouded in the scent of cigarettes and perfume, was a woman so beautiful she seemed a bit too dazzling for the morning streets. Recalling the voices from last night, the scene made perfect sense.
