We climbed the apartment stairs.
Yuna's steps were lighter than they had been when we left for school this morning.
The moment the door to Unit 203 opened, she immediately took off her shoes and arranged them neatly in the genkan.
She still clutched her blue bag to her chest.
I stepped inside first and placed the keys on the small shelf near the door.

"Wash your hands."
"Okay."
Yuna went to the small kitchen sink.
The tap turned on.
The sound of running water filled the cramped room.
I hung my work jacket on the back of a chair.
A few seconds later, Yuna returned.
Her hands were still slightly damp.
She opened her bag and pulled out the gray bento box.
It was empty.
She handed it to me.
I took it and turned on the tap.
Water hit the plastic container with a soft patter.
I took the kitchen sponge.
I began to scrub the inside.
Beside me, Yuna stood slightly on her tiptoes so she could see into the sink.

"Yamada came to my desk," she said.
