Gu Yan: Mo Yiqing, meeting you is the biggest disaster in my life. It is like a poison, it penetrates deep into the bone marrow and is unforgettable. It is impossible to escape or forget. Mo Yiqing: Gu Yan, I don't think you understand that feeling. I know that my heart will be very painful if I do this, but I just can't help but hurt you again and again. I know that you came to me this time with a purpose, but remembering that this is the only way for me to get you back, I have no choice.
