Today, A Yao's family was expecting someone: her older sister's blind date. A Yao was curious. She had never seen a blind date before, but judging by her sister's attitude, she didn't want to go. She looked thoroughly unhappy. Their mother poked her sister on the forehead and told her to be nicer, but her sister refused to listen. Someone outside called for A Yao's mother, and three people came in: two middle-aged women and a burly man. He looked fierce, with a scar on his left cheek. He was smiling, but his grin was frightening enough to make a child cry. A Yao's sister glanced at him and lowered her head. A Yao knew her sister wasn't interested in the man. But he wasn't looking at her sister either. He was staring at A Yao, who was watching the scene unfold from the side.
