I thought it was a rebirth at the end of my school days, but who would have thought that the opening would be directly transformed into Cthulhu: the strangeness of going upstairs and going downstairs, the strange movements of friends, the weird teaching building with cement-sealed windows, and the sudden appearance of weapons and prompts. Ridiculous scene design. The origin of the strange letters, the strange atmosphere in the bathroom, is this an iron rice bowl for pie-in-the-sky, or a trial ground to test people's hearts. Can we come out?
