My name is Yiying, I was born in a small town. One day I received a letter from a woman named "Nightingale" who asked me to participate in a carnival game. It contains my lost memories and the people who are most important to me. My heart is moved. But when I knew the true meaning of that game, I was scared and I wanted to retreat. But the facts never allow me to do this. By accident, I got the King of Glory system. Can this help me escape? But all the mysteries and friendships in the manor. I chose to stay and help everyone.
