When Lin Che stepped into Xinghui Academy, he just wanted to spend his high school life quietly. However, a magic clock that always stops at 8:17, a missing principal who looks 70% similar to him, and a weird birthmark on his chest that will heat up at critical moments, all silently tell a secret buried by time.
Student Council President Ye Shiluo's antique pocket watch can temporarily freeze time, but at the cost of his own life; the library's intelligent system "Book Spirit" said an inexplicable "Welcome back" to him; and those mysterious nosebleed illusions are always accompanied by broken clock faces and twisted hands.
"Time will crack, and you are the crack."
When Lin Che found himself trapped in an infinite loop called "Time Cocoon", and when he faced the "replica" of Ye Shiluo who was distorted by reality, all the puzzles seemed to point to the principal who disappeared three years ago and a tragedy that was deliberately covered up.
In this academy where time is intertwined, Lin Che must solve the mystery of her life experience, find the mysterious figure named Shen Li, and prevent a time disaster that can tear apart reality.
Time will not wait, but the hand of fate has begun to turn back.
