Gristly's Things

I like a good enemies turned to lovers kinda thing but can anyone recommend a manga/manhwa/novel with Lovers turned to enemies trope?? I tried searching in google but it just gives me the enemies to lovers trope (╯°Д °)╯╧╧

I want to read about the pair's yearning as they feel that sharp pang of nostalgia. Haunted memories, betrayal, the terms of endearment that slip out in unguarded moments. The tragedy of irreversibly losing something once beloved. Longing for the the people they used to be but at the same time filled with vengeful resentment.
