One is running wildly with the ball, the other is trying hard all his life to get it back

Snippet:
"Mommy, is this the scumbag you said was the one who sown me?"
When Ling Muchen saw the miniature version of himself in front of him, his face turned black from shock.
"Very good, you are getting bolder and bolder. You are very strong. You dare to run even if you run with the ball. I admire you very much. And boy, I am your father. If I am a scumbag, you are a little scumbag."
Concept: Love should be sweet from beginning to end
