At the end of an alley in Kyoto that is forgotten by tourists, there is an old store called "Shinmono". The old man in the shop is not repairing ordinary cracks, but the remaining memories and emotions in the artifacts - the "heart threads" that have been used for a long time and carry people's joys and sorrows.
A Tokyo girl walked in with her grandmother's old pocket watch. My grandmother suffered from Alzheimer's disease and no longer knew anyone. She only clutched the watch that had been dormant for 60 years day and night and refused to let go. The girl wanted to know what kind of secrets were locked inside a watch that wouldn't move.
The moment the old man repaired his pocket watch with "Threads", time went back - a youthful oath cut off by the war and a silent waiting that spanned an entire century slowly unfolded in front of the girl's eyes. It turns out that the brain will forget some memories, but the heart will not. And what she wants to do is to fish out this heavy waiting from the bottom of a person's heart, so that someone can finally hear it.
This is a story about forgetting and inheritance. Some farewells take a lifetime to arrive; and some answers are worth looking for across three generations.
Concept: The brain will forget some memories, but the heart will always remember them. The real farewell is not to forget, but to pass on the things worth remembering from generation to generation.
