Tennis Back to the Top

A former professional tennis player who retired due to injury. Although I am not willing to give in, there is nothing I can do. Unexpectedly, he inexplicably obtained a tennis system that could cure his injuries. And wanted to take him to a different world where tennis is respected to gain confidence, and then bring him back to reality and return to the top. What would he choose? Author: My writing skills are limited and certainly not as good as most writers. The description of tennis content is not as good as that of writers who specialize in tennis topics. But, I just hope that someone can watch it, even if it's just one person. Someone other than me.
