The trainer, whose time is running out, just wants to survive

Kitano Ryuichi, as a trainer, is not interested in things like heavy horse racing or Shura racing, because he has one top priority - he will not die soon.
Kitano, who died young due to a congenital disease before time travel, could only live to the same age as before he time travel, even if he traveled to the world of the horse racing girl, and then died of extremely painful illness.
But Kitano just couldn't die.Not only that, every time he dies, he will be reborn in the next era of the horse racing girl, and then repeat his painful life for more than 20 years.
Gua!You can't do this!Kitano is in pain and thinking about it. He must get rid of this endless painful life!
The only way that Kitano can change his disease-ridden fate is to keep racing the racehorse. The more races he wins, the longer Kitano will live!The more you want to change your physique and become a healthy person!
However, Kitano had already traveled through N weeks, and when he looked at the horse girls under him who were "monopolizing", losing their glory, and hostile to each other, Kitano felt that his heart was going to die.
Please, don’t do any heavy horse racing, go run and compete, trainer, I just want to survive!
