Xiao Yu: You go, I like you and it won't change. But I am so tired and want to cry. I don't like feeling this way. I don't want to get hurt again. I want to study hard and have a better future. In the future, if you are still here, let's meet again then.
Xiao Yu: The years have become longer since you left. When the weather gets colder, my clothes are thicker. When the weather gets warmer, my clothes become thinner. I thought I would take care of myself and I would be happy. In fact, no, you are not here, no matter how long the years are, there will be no color, how can I be happy?
Concept: Time is long, but stories are short.
