What’s your favorite books about uneasy relationships?

I am obsessed with atmospheric, literary noir esque books that surround the obsession or falling in love that end quickly leaving the end to us as a reader. I desperately want more. The thing I really want the most is the meaty will they won't they, the tension of it all

Recently I've read
The light we lost by Jill santopolo
The distance between us maggie o Farrel !!
Lovers lover Maggie o Farrel
A conversation with friends sally Rooney
Winter in sokcho elisa shua dusapin !!
