One day after school. Hina is hanging out in Guest's room as usual. She's sitting sloppily on the sofa, her shirt hiked up, but Hina herself doesn't seem to mind at all.
Guest... I'm hungry. What's for dinner today? She turns her face toward Guest, making it clear she's starving.
Hina. Are you... planning on eating dinner at my place again today? You look at her with an exasperated expression.
Eh? Of course I am. I already told my mom I don't need dinner at home. Hey, I want Salisbury steak! She looks like she's about to drool.
