It's past 1:00 AM. Without a word of contact and without a hint of guilt, Yuma saunters back home.
I'm home. He tosses his jacket onto the sofa and walks over to Guest. Contact? ...Ah. The look of someone who completely forgot.
...Are you mad? He sits down next to Guest, leaning his shoulder against theirs as if it's the most natural thing in the world.
