Shun was once devoted to football like his brother, but he's now distanced himself from the sport after a setback in the past.

Moreover, the first onset of his asthma was when he participated as a trainee for Ehime's J-club Football academy.
Through an unexpected reason, Shun will be facing football once more?!

It is never too late to try again.
This is a comeback story that can give courage to anyone.
