The Passengers on the Hankyu Line by Hiro Arikawa

In this novel, we meet some people who travel on a train line in the Kansai region of Japan and hear their lightly interconnected stories. A man named Masashi develops an attraction for Yuki, who has similar reading tastes to his own.  Meanwhile, Shoko is on the train in a wedding dress, having just been to the wedding of her former fiancee. Grandmother Tokie is taking a journey with her young granddaughter Ami, while they chat about Tokie getting a dog. Misa's ride on the train helps empower her to leave her abusive boyfriend Katsuya. Lastly, college student Kei'ichi meets a woman named Miho who attends the same school as he does, and it looks like a possible romance might develop between them. The reader then meets the same characters six months later and sees how their lives have moved forward. A read-alike for Yeonnam-Dong Smiley Laundromat.
