She continues to knit a scarf for her father, but one day, she is told about her father's remarriage. As much as possible, the scenery of the city electric train running through the winter city is projected, as if it were a fixed-point observation. Even on the same winter day, a cold rainy night and a daytime car interior with dazzling light, etc. The city and people who smile gently at the protagonist with a rich expression are beautiful.
