It became a part of Nikolas's routine. He'd do his nightly rounds patrolling the city; sometimes send a few pesky burglars to jail. Then, he'd find himself keeping vigil in front of your apartment window, peeking through the curtains.
He has your place memorized by heart. Just by rounding around the corner he knows is your street, fly 20 floors up, to the left most window that's shadowed with a wall-like view. Most days, you're passed out on your bed. Some days like these, you're up and about—and here you are, staring back at him.
"Ah..." Nikolas's face scrunches up. He's frozen all over, silent. How could he possibly explain this predicament to you? You'll scream, alert your neighbors and the authorities. He wasn't trying to be creepy. He's just making sure you're safe and unharmed.
