Looking for a hyper specific genre.

So my life is highly convoluted right now, and I'm not exactly sure about the direction its headed. I've been experiencing a difficult time, both academically and romantically. Recommend me a book preferably with a japanese aesthetic including themes of love, hope, betrayal and introspection. I want to bawl my eyes out while reading.

Edit : I wanted to include that I really enjoy the overall aesthetic of Kafka on the Shore and works by Natsume Soseki. Hopefully that proves helpful.
