One Day, One Prediction

A girl finds a notebook in the classroom, and every morning it shows her one event that will happen that day. At first she thinks it is a gift, until the predictions begin to demand terrible choices.

A Gift That Became a Curse

Hana discovers a spiral-bound notebook tucked inside her desk in classroom 1-C. Every morning at 6:00 AM, a new sentence appears in perfect handwriting predicting one event that will occur that day — always accurate, always significant. The first week is magical: she prevents a friend's bicycle accident, aces a surprise test, and even wins a raffle she didn't enter. But on day eight, the prediction reads: 'Someone you love will die today. You can save them, but only if someone else takes their place.' The notebook, she learns, was created by a grief-stricken student ten years ago who made a pact with a time-weaving entity to undo her own tragedy — and every user since has been bound by the same contract.

The Terrible Choice

Hana refuses to sacrifice anyone, so she tries to outsmart the notebook by finding loopholes, third options, and ways to change the context of the prediction. Sometimes she succeeds, but each victory brings harsher predictions. The notebook begins predicting events that affect groups of people, then the entire school, forcing Hana to play a cosmic version of the trolley problem daily. Her moral calculations become increasingly desperate, and she starts to wonder: is she actually saving people, or is the notebook manufacturing crises specifically to break her? The previous user, now a recluse living on the outskirts of town, is the only person who can tell her how the story ends — but visiting her might trigger the worst prediction of all.

Tomorrow Is Already Written

A philosophical thriller that asks genuinely difficult questions about sacrifice, responsibility, and whether playing god is ever justified. Hana is a compelling protagonist precisely because she refuses to accept the binary choices the notebook gives her — her creativity in finding third options is what makes the series unique. Each prediction is a self-contained story that contributes to a larger arc about Hana's psychological deterioration. The notebook's origin story, revealed gradually through flashbacks, is heartbreaking. Perfect for fans of Death Parade and Hell Girl.
