Many years ago, when Lin Yanjing was still little, he once used his pocket money to buy a Cornetto ice cream. Before he could take a bite, a Border Collie puppy snatched it and knocked him to the ground. He burst into tears right there. Through tear-blurred eyes, he saw a little girl help him up and apologize over and over. He had long since forgotten what she looked like, but he still remembered how warm her hand was. It turned out that the little girl from back then was Sun Siyuan. Their fate had begun so long ago.
