Even today, Liu Manli still remembers the scene when her heartbeat quickened for the first time.
It was twenty-four years ago, during fifth grade of elementary school, on a weekend, when her father was very busy and she was swinging alone in the yard.
A tall and strong-looking, handsome boy with an honest smile approached her. He said his name was Lei Ting, and from that day on, he would be moving to this area and would be responsible for protecting her safety.
The twelve-year-old girl was in her carefree early adolescence, and despite feeling shy, she still tried to shoo him away with a stern face, but the boy just stood by her side, grinning foolishly, unwilling to leave.
