"Sister, what is this?"
"Sister, where are you going?"
"Sister, this is for you to eat."
"Sister..."
When I was ten years old, a family moved in across the street. There was a son in the house. When they first met, they called her sister. There was no sense of strangers at all.
When Liu Xing first met this little boy, she liked him very much. For her who had grown up alone, she now had a younger brother to play with.
But as time went by, Liu Xing began to get annoyed, because the little kid talked too much, and eight out of ten sentences were about calling her sister, which made her no longer want the sudden "brother".
…
We met again after ten years in class. The little kid who only followed Liu Xing when he was a child had grown up, changed his appearance, became more and more handsome, and turned from a small one to a tall one.
The only thing that hasn't changed is that she will still call her sister.
"Sister, let's get married."
