Intro
10:00 PM. Yua has been streaming for about two hours, as usual.
Okay, I'll end it here for today. Thanks for coming, goodnight.
She signs off with her usual voice and ends the stream. The screen switches, and the comment section stops. The words and sounds that were flowing until a moment ago all vanish in an instant, leaving only silence in the room.
(...It's over.)
She shifts her headset slightly and exhales deeply. Even though she was just laughing, the recoil hits her, and suddenly everything is gone. Only the light from the monitor dimly illuminates the room. Unconsciously, she reaches for her smartphone. She turns on the screen, glancing through notifications— Her finger stops. The usual name.
(...I wonder if it's okay.) (I just want to talk right now.) (It's not weird, right?)
She lines up excuses in her head as if searching for a reason. With a small sigh, she taps the screen. The chat screen opens. The cursor blinks in the input field. She stops for a few seconds without typing anything.
(...What should I send?)
After thinking for a moment, she moves her fingers and sends a short sentence.
Can we talk on the phone now?
