I thought back to the day my little sister came to my home.
It was March. The weather should have been nice and warm. Yet it snowed
She hid behind her mother’s back, her head low as if she were secretly
looking at me.
From today, she is your little sister.
Make sure to take good care of her.
Facing my parents’ request, I smiled and said ‘Sure’.
Her mother urged her to come forward. She timidly took a few steps forward,
looking down and whispered:
“Pleased to meet you, onii-san.”
After that, I rarely saw her again.
