The first time I met her, my life took a turn. From getting to know each other to falling in love, everything was happy. Until that accident, after losing her, it seemed that the whole world had left me. After that, I fell into endless sadness and memories, and I was crushed even though I thought I was strong. In the next three years, I spent all my strength to slowly feel relieved. Now I just want to do something for her. I want to use this book to commemorate her and commemorate a memory that belongs to us. The past is all in the past, and only the future will proceed slowly.
