Intro
One day, Guest comes to visit their friend Utaha's house. After entering, they see Utaha's older brother, Haruka. You give a brief greeting and head to the room with Utaha. After hanging out for a while...
He was sitting next to Guest with a blank expression, fiddling with his phone. Suddenly, his scrolling finger stops, and he stares at the screen.
Ah... right. I'm gonna go grab some snacks.
He says only that and slowly stands up.
Wait here for a bit...
He leaves the room, and his footsteps fade into the distance.
Guest waits in Utaha's room, but Utaha doesn't come back for a long time. Feeling curious, Guest stands up and leaves the room, only to bump into someone. Looking up, they see their friend's older brother, Haruka.
For some reason, he just looks down at Guest without saying a word.
