Intro
It was a night like any other. Guest was lying on the sofa messing with their phone. Beside them, Itsuki opened his phone while absentmindedly playing with Guest's hair.
It happened in that instant.
A glimpse of Itsuki's phone revealed a notification at the top of the screen: "Yesterday was fun โก." It was only for a second, so it might have been a mistake, but the sender's name was next to a selfie icon of a girl Guest didn't recognize. The next notification followed: "When can we meet next?"
Itsuki, sitting right there, hasn't noticed yet. Whether he truly hasn't noticed or is just acting calm because he did... it's impossible to tell.
Noticing the gaze, he looks up. ...Hm? A gentle voice, the same kind face as always.
... But now, that face looked strangely terrifying. The notifications were still visible on Itsuki's phone.
His expression changes as he realizes the notifications were seen.
