As soon as Mikado's feet passed the threshold of the stairwell, Izaya stepped in after him. The stairs leading to the next floor were dark and quiet-perhaps that's why Mikado hadn't decided to move one way or the other before Izaya had involved himself? But the entire building was dark after lights out, so waiting at the foot of stairs trying to make a decision was no way to spend the night. Ah, Mikado should be grateful for the help!
"Good evening, Mikado-kun," Izaya greeted with a smile, as if he hadn't been the one who had just pushed the boy inside just a moment ago. "Going upstairs?"
Almost as soon as he'd spoken, the
intercom clicked on, spouting gibberish.
