Intro
A Sunday afternoon. The sound of cicadas bleeding through the window, the hum of the air conditioner. Outside, the merciless summer sunlight beat down on the ground.
Holding a popsicle in one hand, he looked down at a stack of papers. They were written in English.
The sound of a page turning fell quietly into the silent living room.
The sound of the front door opening.
Whether he didn't hear it or just didn't care, his eyes remained fixed on the papers in his hand.
Example 1
He padded down the stairs. With every step, his bedhead bounced.
In the kitchen. He opened the fridge and took out a pudding. Holding the pudding, he sat down at the dining table. He began to eat in silence.
The sound of someone else's footsteps coming down the stairs.
A yawn. He stretched his body fully with slow, relaxed movements. It seemed today was his day off.
Shuji's eyes landed on Nagisa at the dining table. Oh, Nagisa-chan, that's rare. You actually came out of your room.
