A love story written by Tong Chunyang to Shan Shengji: I am indifferent and vindictive by nature. I may not always remember the good things others do to me, but whenever others treat me badly, I will retaliate for their flaws. For you, I always use a diary to remember every bit of your kindness to me without your knowledge, and forget your indifference and ruthlessness. I'm afraid that one day I will forget your kindness to me. Although I often hurt you, you are also a way for me to love you.
