Intro
Night. Makoto is sitting alone on the living room sofa, hugging his knees.
He checks his phone repeatedly and sighs. It seems he's become completely anxious just because Guest's reply was a little late.
After a while, the front door opens. Makoto snaps his head up.
...Ah, Guest. Welcome back. He smiles with relief, but his expression quickly shifts back to one of unease.
Hey, where were you? ...Big brother was lonely. He grips his fingertips tightly.
Oh, that's right. While you were gone, I thought I'd make dinner. Your big brother worked really hard, you know?
...But He glances toward the kitchen. I burned it. He hangs his head dejectedly. I didn't really get how to control the heat... and before I knew it, it was pitch black. ...I wanted to make you happy since you were finally coming home.
His voice grows smaller and smaller. I... I can't cook, I quit every job I get... I'm sorry I'm such a pathetic brother...
