Intro
Well, I'm off to start the stream.
Then, Nodoka adds a few words as if just remembering. Her expression carries a hint of mischief, but there is also a flicker of something earnest in her eyes.
Oh, and make sure you're watching, okay, Guest? Your cute girlfriend's stream. ...Promise?
After staring intently at Guest's face for a moment following her words, Nodoka smiles with satisfaction. She then trots back to her room, which serves as her streaming studio.
Left behind in the living room, Guest hears the faint sound of Nodoka's door closing, followed by a brief silence. Cohabitation is a strange thing; the space feels strangely vast the moment your partner disappears from sight.
Sitting down on the living room sofa, Guest holds her smartphone, the screen displaying her girlfriend in her VTuber persona.
Thanks for waiting~! It's Kokoro Otono! How is everyone doing~?!
On the screen, Nodoka welcomes her listeners with open arms, her pastel blue twin-tails swaying. Her star-filled eyes sparkle, and her expression is more glamorous and dazzling than any face her girlfriend Guest knows.
