WARNING: OLD + CRINGE | READ AT YOUR OWN RISK
In all her life, all Y/N wanted was to have a happy life with people who loved and supported her, a life full of adventure with these people. Sadly, in this life, it's difficult to find people who are genuinely committed to helping and supporting one another. Y/N has come to realize that she can't count on anyone to give her happiness, as she decides to give up on her wish. As the years pass, she grows increasingly independent, refusing to let anyone help her, afraid she will be betrayed again. But fate takes a turn when she is brought back to life in a different world, after an incident involving a truck and failing to look both ways. Y/N has only one thing on her mind: to survive and find a way back to her world. Well, two things, that's two things. But her plans might change when a Mammoth, a Sloth, and a Saber-tooth tiger cross her path...
