In an underground cafe on a certain street corner in Tokyo, there is a mysterious seat that can travel through time. Just pour a cup of hot coffee and sit quietly for a while, and you can go back to the most regrettable day in your life. But the rules are strict: you must return before the coffee gets cold, and you can't change the outcome. The boyfriend will still leave, the lover will eventually lose his memory, the loved ones will inevitably be separated forever, and the mother and daughter are destined to miss... The four guests with regrets touched another form of love in time and space, allowing those misunderstood truths to surface: those who traveled far away buried the promise of reunion, those who forgot left their affectionate vows, those who passed away entrusted their unspoken dreams, and those who were not yet born have the power to continue their lives. Time is as irreversible as the coffee becomes cold, but every bitter taste teaches them to reconcile with their fate: some farewells are not for the end, but for people to move forward with known love.
