This Weak Teen Has a Super Football System

Amu has asthma bad enough that the rich kids at school treat him as entertainment. During one attack, with his air running out, a football system opens in his head and offers him a way out of being nobody. He builds a team from the players nobody else wanted, the ones cut from squads or written off, starting with Xiaocao in goal. For a coach he goes after a former national player who was forced out of the game over charges he never committed, and he does not take no for an answer. Then he trains, on top of schoolwork, harder than his lungs are supposed to allow. The school favors the wealthy squads. Referees make calls that are not close. In one match his side plays a man down for most of the game. None of it stops him. Amu and his players work their way through the powerhouse teams of the league one at a time, and every prejudice about who belongs on that field gets tested against what they actually do with the ball.
