Amusansan

Toyama's beloved sweater, knitted by his late wife, has been stained by his grandchild. Even dry cleaning can't remove the stain, leaving him at a loss. Suddenly, he remembers his subordinate, Morimoto, knitting every weekend at a coffee shop with a calm expression he's never seen at work. Toyama is torn between wearing the stained memento sweater and throwing it away. Seeing this, Morimoto murmurs, "Why don't you just unravel it?" That single sentence sets Toyama's life, which had been stagnant since his wife's death, in motion again. And so begins an unexpected exchange between two people of different ages and values, all through knitting. (Source: Shogakukan, translated)
