America: I'm Really Not Crazy

Levi traveled through twenty-five years and finally ushered in an important turning point in his life on his twenty-fifth birthday. Good news: I have a tumor on my brain. Bad news: There's a system in place. Just when Levi decided to release himself completely and enjoy the countdown to his life, the nasty "Villain System" forced him to continue his life again and again. "Hey! System! You bastard are destroying my understanding and happiness of life!" [You are a little too extreme...] This is the story of a time traveler who only had one month left to live and decided to spend the rest of his life blooming like fireworks, but was forced by the system to live on. PS: The protagonist is not mentally ill or insane, he just wants to live as he pleases, that's all.
