Death Is My Only Gift

(Japanese light novel) (slow-paced) (not a power fantasy) (multiple female leads) (death regression) (mild love triangle)

In 2159, on Blue Star, Lanyan Academy is a magical school like a city within a city, bringing together geniuses, outsiders, and people burdened with secrets from all over. The young Wan Feng only wants to live an energy-efficient, ordinary life without getting into trouble, but after a sudden death at school, he is drawn into inexplicable time regressions and a cycle of death.

As one bizarre incident follows another, Wan Feng has no choice but to keep trying to change the tragedies that are destined to happen within the limited time he has.
