The Hidden Tennis Master: A Hellish Start, A Grandmaster's Finish

Yueqian Kuaidou transmigrates into a boy from the slums. His parents are seriously ill, his younger siblings are starving, and his gold-digging girlfriend looks down on him for being poor.

After binding to the Grandmaster Development System, he can copy an opponent's skills just by pointing out flaws in their tennis. He starts out as a court sweeper.

At the Seishun Academy courts: “Tezuka, your shoulder is injured.” He copies the Zero-Shiki Slice.

At the Hyotei gates: “Atobe, your insight has a blind spot.” He copies the Waltz Toward Destruction.

He gives the hot-tempered Kintaro advice while running a street stall, and opens Ryoma's eyes while delivering food.

When the U17 coach sees the people he once advised, he's stunned: “Coach Kuaidou?!”

His gold-digging ex-girlfriend tearfully begs to get back together. Kuaidou shows her his Rolls-Royce key. “Sorry, the passenger seat is taken by my new girlfriend.”

When reporters from around the world ask the secret to his success, Kuaidou hoists his broom and smiles. “Nothing special. I just got good through practice.”
