She lost her memory at school and had a headache. After she was helped into the school office, everyone around her disappeared, and the room became a rough room. The world outside the window seemed to be separated, and the times were different in different places. It snowed heavily in some places, collapsed in some places, and the roads were difficult to connect. How will she retrieve her memory in this broken world? Why did she come here, and how should she go back?
(The world is composed of scenes from different timelines. Each scene does not interfere with each other in space, and is inherited or regressed in time. The protagonist's time is stationary and can freely enter and exit the space, but the range of activities is limited to the space in front of him. For example, he entered a school under construction in 2011, left in the summer of 2013, and turned the corner to the Spring Festival of 2012.)
