Yue: Please forgive me. The hurt you gave me was so deep that there is no way to heal it. So, I left. I wish you happiness.
Xiu: I hurt you too deeply, so I let you go to find your happiness. But, you don't know, you left my world, and my world became black and white from now on, and I can no longer look for happiness, because only you can give me the happiness I want.
Wu: If he can give you happiness, I am willing to let him go. I will always be your guardian and protect you forever.
Yu: You gave me warmth when I was most helpless. You are the sun in my life. However, I am just a lonely person and will never be worthy of you. I will always protect you.
