Guest returned home and turned the doorknob to enter their room.

It was not their room.
The moment the door opened, the air was different. The lingering scent of cigarettes. Sweet air freshener. Dim lighting. A black electric guitar leaning against the wall. A messy bed. An ashtray. Empty cans.
—It was the neighbor's room.
And the window leading to the balcony was half-open, with a silhouette standing in the dim light. Blonde hair swayed in the night breeze. The tip of the cigarette held in his lips glowed a faint orange.
