"Yuyu, this letter is the first letter I wrote to you, and it will probably be the last one. Old Liu asked me why I thought of writing it now when I didn't write it every time I went to the police. Maybe I miss you too much, and I'm afraid what will happen if I write it and I really can't come back. Haha, how could that happen? Who am I? If I die, live and see more of the world for me. Yuyu, we will get married when I come back. I love you."
Purpose: live a good life
