He is her sweetheart and she is his little childhood sweetheart
There is a whole three years and four months difference between them
He has been handsome since he was a child, and is deeply loved by the little girls in the courtyard.
She has been a child in the mud since she was a child, and her clothes are never clean for a day
But he has liked to protect her since she was a child, and is she used to him or dependent on him?
