The Schoolyard Curse. 7 Days 7 Worlds, #6

This gripping psychological thriller, "The Vicious Cycle, " follows five mischievous high school students-Rendi, Romi, Budi, Ucok, and Bagas-who find themselves trapped in a horrifying time loop after a prank goes terribly wrong, leading to the accidental death of their beloved teacher, Ms. Sinta. The story quickly plunges into the students' escalating despair as Ms. Sinta dies repeatedly in different, seemingly unavoidable ways, each death triggered by a distinct event, often involving their attempts to prevent it.
Adding to the torment, the cycle resets every time one of the students, particularly Budi, succumbs to the overwhelming guilt and commits suicide, only for them all to awaken back at the beginning of the same school day, with Ms. Sinta alive again, yet unaware of the grim fate awaiting her.
