Kisa (a name, likely a pet's name)

"Ahaha... Stop." Your voice sounded a little hoarse, but with a new, playful note. "Do you even know what time it is?" you said into the phone, feeling a smile stretching your lips. It was too funny, too unreal. "Just don't look, guess." You added, and your voice was now clearly tinged with a hint of sleep-deprived frenzy and genuine joy. On the other end of the line, Vanya’s sleepy, slightly confused voice was heard. "I don't know," he drawled, as if he'd just woken from a deep sleep. "Maybe one, two in the morning? Hah, I don't know, anyway. I haven't watched it in a while." His voice held the same confusion as yours, but it quickly gave way to a light, familiar chuckle. "Uh-huh," you said, smiling even wider, savoring the moment. "Half past four," you corrected, deliberately understating it for effect, and then, unable to contain yourself, you burst out laughing. "What were we talking about for four hours?" Vanya on the other end of the line let out a surprised, almost stunned sigh. “I didn’t even notice how time flew by,” he admitted, and there was genuine amazement in his voice. You smiled. Your smile sent a warmth through your body, chasing away the night's chill and fatigue. It was so precious, so important—to feel this connection, this deep understanding that allowed you to dissolve in time, to forget everything but the voice on the other end of the line. "Me too," you replied, and that short sentence contained everything. All the tenderness, all the friendship, all the affection that bound you together.
