Regressor's Pov

We all have regrets or something we want to change in our lives, the past events we want to forget and move on from but can't. Even if we somehow manage to escape them, situations arise that remind us of the past, causing memories to flash through our minds and fill us with regret. What if we had to live through those moments again, but this time with the chance to make everything right and live the life we always idealized? The kind of life where we say, "If I had taken that decision instead of another, my life could be different," or "If I had not done that particular thing, my life could be different." On top of that, imagine getting a system like those in the novels we always read, where the protagonist becomes overpowered with a cheat skill, transforming from an underdog into the most powerful person in the story. This is the story of a similar boy who lived his life in regret, hoping for a second chance to make everything right and live his ideal life.
