This World Isn't Normal

I often dream of a girl with long hair that reaches her waist. When I wake, I always feel a sense of loss.

Then one day, I woke up to find that everyone around me had vanished!

Panicked, I searched around the town and met a girl named Liu Yixia. In the end, I joined a group called the Survivors' Alliance.

Eight people, brought together in this abnormal world by the flaws in their personalities. But what will it take for us to return to our original world?

Perhaps the "key" is already in our hearts.
