There is no regret medicine in the world. Once a mistake is made, it cannot be changed, it can only be faced.
What if it could? What if you could go back in time? What if it could be changed again?
"Keep going and you will have a new story. Maybe you and that person will meet again.
Turn around and walk back. You can intervene and maybe change your life?
But no one ever goes back. I don't know what effect a small butterfly will have. I don't even know if history has an automatic repair function. Everything is unknown. Do you want to go back? "
The choice is in your hands, how to choose?
All decisions are made for the person you care about.
