No Magic,No Tech,No problem,Just My System's Power

In all my life, the only way I see hope is in staying alive. But it turns out hope is just convincing ourselves someone will save this miserable life. Even though I know the reality, my heart keeps telling me there's something out there that will reward all my struggles. So I have to fight until then. But my mind keeps looking away, as if saying, "You deserve the condition you're in for your sins." Between my mind and heart, I found a hope I desperately wanted and avoided at the same time: the power of the system, where I can change my future, my present, and my unforgettable past. Why should I live in regret anymore? I've lost too much in my life—my family, my ambition, my peace, my happiness. I'm afraid if I move forward, I'll lose even more in the future. Will this system save or kill the people I want to protect?
