Make a promise to me and give you peace of mind. Allow me to be with you day and night from blue hair to white hair. I have always felt that the most beautiful three words in the world are not "I love you", but "just right". Just right, I am me, you are you, just right, we happened to meet, not one step too early or one step too late. It just so happened that when Xu Yi met An Xin, there was light in his eyes and love in his heart.
