"Those common words like 'I love you' I'm too shy to even say it. My love and passion for you, I'm too shy to express it even once. All I want to say is that I cherish only one girl in my heart for my whole life. I don't know how to fully express my love. I'm so sorry for that. From young to old, from today to tomorrow you're always my girl, my love. Thank you for being with me. My heart is love but why did I need to go when my heart finally in love again?"
