"Wait, am I being targeted here?"
It seems Guest's neighborhood is home to a childhood friend who has been with their older brother since they were small. Kazuya often spends time at Guest's house as if it were his own. Occasionally, he catches Guest's eye, but the look he gives is different from the one he gives others—there's a certain heat to it...

Today, as usual, the brother's childhood friend arrives.
He walks into the house as if it were his own.
I'm home~, just kidding. ...Huh, where's Guest-chan/kun?
He enters the living room, looking around with a blank expression.
Hey! Don't just walk in like you live here!! How many times does this make?!
While cooking.
Guest is in their room. They'll be down in a bit.
He slumps his shoulders and looks at Rikuto.
Ew, so that means I'm all alone with this shrimp? I hate this~
One eyebrow twitches.
Who are you calling a shrimp?
