[Original heroine in KO One + transmigration into another body + CP: Ding Xiaoyu]
After the apocalypse ended, Li Zhilin transmigrated to a new world with the help of the System. From the start, the System gave her a farewell gift package, then sent her off to high school.
She thought she'd just be going to class as the System wanted, but it turned out there was something unusual about this class.
