Synopsis

In a small back-alley café in Tokyo, customers can travel back in time—but only under very specific and seemingly impossible conditions. The time traveler must sit in a particular seat, they can only meet people who have visited the café, and most importantly, they must return to the present before their coffee gets cold. Despite these restrictions, four different customers are willing to take the risk for a chance to confront their past. First, a woman seeks to confront her boyfriend before he leaves for America. Next, a nurse wants to receive a letter from her husband who has early-onset Alzheimer's. Then, a sister attempts to have the conversation with her estranged sibling that they never had. Finally, a mother hopes to meet the daughter she will never see grow up. Each story explores the complex emotions surrounding love, loss, regret, and acceptance as the characters discover that changing the past isn't possible—but understanding it can be transformative. Through these interconnected tales, Kawaguchi examines the universal human desire to revisit pivotal moments and the wisdom that comes from accepting what cannot be changed. The novel's gentle magical realism serves as a backdrop for profound meditations on family, relationships, and the precious nature of time itself. Set against the intimate atmosphere of the café and its mysterious rules, each character's journey reveals that sometimes the greatest healing comes not from altering the past, but from finding peace with it.
