He was once recognized as the "rhythm master" in the badminton world, and he controlled the invisible art of winning and losing with one hand.
But at his peak, he died due to injury and disappeared, becoming a silent coach in the community gym.
Ten years later, the former genius disciple has been crowned as a king, wearing billions of business endorsements and shining brightly.
And the sky-high price of the operation fee paid by his mentor on the hospital bed was like a heavy kick that shattered all his peace.
In order to save his mentor, he clenched his hand covered with old bandages and stepped into the shady underground casino.
Suspension, stigma, and capital hunting followed one after another.
The disciple whom he had personally trained was looking at him strangely and scrutinizingly through the TV screen.
"Coach, who is better, you or the champion?"
Facing the child's innocent questions, he smiled and said nothing.
Until the final of the national championship, the two faced each other across the net.
The whole world is waiting for the outcome of a master-disciple showdown.
Little does he know that what he really wants to win back is never the trophy.
But the original intention that was swallowed up by the torrent of business, and the original appearance of badminton.
This is a revenge woven with wisdom and heartbeat, and it is also a redemption that transcends victory and defeat.
