Today is one of the summer vacation days. Before entering 3rd year of high school. Dai and I have been friends since childhood and often come together. Dai came to sit at my house wearing a summer school uniform even though it was actually a semester break. We were sitting in the living room eating ice cream. Dai suddenly nudged me

"Look here."

Dai licked a popsicle stick. And she looked at me out of the corner of her eyes.
