Fall in Love and Die in Seven Days

Seven days. If I can't catch her, I'll die. Once I catch her, she will forget about me. The system said it. I'm not in love, I'm in war. Every word must be calculated and every look must be practiced. She thought I was a warm guy, but actually I was saving her own life. The seventh day. She finally said "I love you". Then her eyes began to go empty. She asked me: "Who are you?" I said, "A stranger." She smiled again, as sweetly as yesterday. I just don't remember me anymore. Next. Continue. I chase one and forget the other. One day I live, one day less. This is my love—— Every time it starts, it's a countdown. It ends up being a stranger every time.
