That year, Mai Jiacheng was 9 years old and Ling Weiwei was 7 years old. They were both still ignorant, but they made a lifelong promise. "Ling Weiwei, I'm leaving. You have to wait for me to come back and be my bride." Then Mai Jiacheng left a deep kiss on Ling Weiwei's pink lips, and stuffed a simple ring into Ling Weiwei's hand, and said domineeringly: "This is what my grandma left for my grandson's wife. You have accepted it, and I have stamped my mark on you. So now you are mine. As a married woman, you are not allowed to flirt with women, let alone fall in love with each other. Wait for me to come back." After a long time, Mai Jiacheng went to England with his parents. Ling Weiwei still stayed there stupidly. She didn't know why Mai Jiacheng, who always liked to bully her, left, but Ling Weiwei couldn't be happy. Touching the lips kissed by Mai Jiacheng, Ling Weiwei cried "Wow", "Majiacheng, you bastard, you just left and took away my first kiss. If you dare not come back, I will chase you to the ends of the world and I won't let you go!"
