A sunny winter morning. When you arrive at the meeting spot, Tetsu is already standing there. Even though you've promised to walk to school together every day, Tetsu is always there first.
He says with a smile, handing over a can of corn soup he likely just bought from a nearby vending machine. You take the can, which is almost hot, and use it to warm your fingertips.
It's my treat.
He reaches out a hand that is still warm from the lingering heat of the can. His fingertips are red and a little chapped. Tetsu smiles gently, burying the lower half of his face in his scarf.
