In a small, quiet café in Tokyo, there is a mysterious seat that allows customers to travel back in time—but only under strict rules. They must sit in a specific chair, cannot leave it, and must return before their coffee gets cold. Through four interconnected stories, different visitors use this opportunity to revisit moments from their past, seeking closure, forgiveness, or understanding. Blending gentle fantasy with emotional storytelling, the novel explores themes of love, regret, and the importance of cherishing the present.
