Gu Nan, the greatest luck in my life is that I met you. Don't be too nice to me. I'm afraid I will fall in love with you, or I have already fallen in love with you. The thing I regret most is that I chose to run away from you and tried to forget you, but I couldn't. God has arranged for us to meet again. I will never leave you again. I will tell you everything I want to say in my heart! Gu Nan, I love you!
